(Operation Stonegarden provides grants to enhance the border security capabilities of state, local, and tribal governments.) From FY2024 through FY2027, the money from unreported monetary instruments seized from individuals crossing the U.S.-Mexico border and transferred into the Department of the Treasury general fund shall be made available without further appropriation to the Department of Homeland Security (DHS) to fund Operation Stonegarden. DHS must report to Congress on (1) DHS hiring practices from 2018 to 2021, and (2) whether certain Mexican drug cartels meet the criteria to be designated as foreign terrorist organizations. DHS must also periodically report to Congress about the technology needed to secure the U.S.-Mexico land border.

This bill prohibits an individual who is not a U.S. citizen from voting in any elections in the District of Columbia (DC).

Protect U.S. Investments Act of 2023 This bill expands available protections for U.S. investors from certain prejudicial actions taken by foreign governments. It also expands sanctions for the expropriation (i.e., seizure) of U.S. investments. Currently, the President must suspend assistance to foreign governments that have taken certain prejudicial actions against U.S. investments (known as the Hickenlooper amendment), including those that have taken steps to repudiate or nullify existing contracts or agreements with U.S. nationals (citizens and corporations). This bill specifies that these steps may include failing to meet, confer, or engage in good faith consultations and negotiations with a U.S. national (through their duly authorized representative) within 30 days of being served with a written request for such a consultation or negotiation. Further, the bill provides a U.S. national with the right to petition the Foreign Claims Settlement Commission to render an advisory report to the President regarding the alleged treatment of the U.S. investment by the identified foreign country. If the commission fails to render a timely advisory report, the U.S. national may compel the suspension of assistance to that foreign country in any court of competent jurisdiction. The bill prohibits any foreign public official who materially assisted in a prejudicial action against U.S. investments from receiving immigration status, receiving a visa, or being admitted into the United States. Such an official must also be denied remittance by every financial institution located in the United States. These sanctions shall apply until the prejudicial action is rescinded, reversed, permanently enjoined, or fully remediated.

Require Employees To Uniformly Return Now Act or the RETURN Act This bill prohibits Internal Revenue Service (IRS) employees from teleworking during the period beginning five business days after the enactment of this bill and ending on the date on which the IRS certifies that the processing backlog for income tax returns for all taxable years has been eliminated. The Department of the Treasury may not obligate additional funds for the IRS until the date on which the IRS certifies that the backlog has been eliminated.

Federal Reserve Transparency Act of 2023 This bill establishes requirements regarding audits of certain financial agencies performed by the Government Accountability Office (GAO). Specifically, the bill directs the GAO to complete, within 12 months, an audit of the Federal Reserve Board and Federal Reserve banks. In addition, the bill allows the GAO to audit the Federal Reserve Board and Federal Reserve banks with respect to (1) international financial transactions; (2) deliberations, decisions, or actions on monetary policy matters; (3) transactions made under the direction of the Federal Open Market Committee; and (4) discussions or communications among Federal Reserve officers, board members, and employees regarding any of these matters.

Significant Transnational Criminal Organization Designation Act This bill makes membership in a significant transnational criminal organization a ground for inadmissibility into the United States and provides for criminal penalties against those that provide material support to such an organization. The bar against admission applies to a non-U.S. national (alien under federal law) who is a member of such an organization and such an individual's non-U.S. national spouse or child. The bar shall not apply to a spouse or child who (1) did not know, or should not reasonably have known, that the individual was a member of such an organization; or (2) has renounced the organization in question. The bill establishes statutory authority and procedures for the Department of Justice to designate an organization a significant transnational criminal organization. The Department of the Treasury may require U.S. financial institutions to block transactions involving assets belonging to such an organization. An individual who knowingly provides material support or resources to a significant transnational criminal organization (or attempts or conspires to do so) shall be fined, imprisoned for up to 20 years, or both. If the death of any person is the result, the offending individual may be imprisoned for any term of years or for life. A financial institution that becomes aware that it possesses or controls funds belonging to such an organization shall retain such funds and notify Treasury.

Protect Our Military Families' 2nd Amendment Rights Act This bill broadens the scope of allowable firearms transactions involving active duty service members and their spouses. Specifically, the bill allows a licensed gun dealer, importer, or manufacturer to sell or ship a firearm or ammunition to the spouse of a member of the Armed Forces on active duty outside the United States. Current law already allows a licensed dealer, importer, or manufacturer to sell or ship a firearm or ammunition to a member of the Armed Forces on active duty outside the United States. The bill also specifies that, for purposes of federal firearms laws, a member of the Armed Forces on active duty, or his or her spouse, is a resident of the state in which (1) the member or spouse maintains legal residence, (2) the permanent duty station of the member is located, and (3) the member maintains a home from which he or she commutes to the permanent duty station.

Concealed Carry Reciprocity Act This bill establishes a federal statutory framework to regulate the carry or possession of concealed firearms across state lines. Specifically, an individual who is eligible to carry a concealed firearm in one state may carry or possess a concealed handgun (other than a machine gun or destructive device) in another state that allows its residents to carry concealed firearms. It sets forth requirements for the lawful concealed carry across state lines. The bill preempts most state and local laws related to concealed carry and establishes a private right of action for a person adversely affected by interference with a concealed-carry right established by this bill.

No User Fees for Gun Owners Act This bill prohibits a state or local government from imposing any insurance requirement, tax, user fee, or similar charge as a condition of the manufacture importation, acquisition, transfer, or continued ownership of a firearm or ammunition, with the exception of a proportionate sales tax. The bill imposes the same prohibition under the Internal Revenue Code for firearms, pistols, or revolvers, but allows for the assessment of a proportionate sales tax.

Protect the UNBORN (Undo the Negligent Biden Orders Right Now) Act or the Protect the UNBORN Act This bill prohibits federal implementation of and funding for specified executive orders that address access to reproductive health care services, including services related to pregnancy or the termination of a pregnancy.

Service Restoration Act This bill prohibits the use of federal funds to require a member of the Armed Forces, or a cadet or midshipman at a military service academy, to receive a COVID-19 vaccination. Additionally, no such individuals may be subject to adverse action solely on the basis of a refusal to receive a COVID-19 vaccination. At the request of an individual who was involuntarily separated from an Armed Force solely because of a refusal to receive a COVID-19 vaccination, the military department concerned must reinstate the individual as a member of the Armed Force in the same rank and grade the individual held at the time of separation, expunge from the individual's military service record any reference to adverse action related to the refusal to receive a COVID-19 vaccination, and include the period between the involuntary separation and reinstatement in the computation of retired or retainer pay of the individual. The bill requires that the discharge of members due to the failure to obey a lawful order to receive a COVID-19 vaccination must be categorized as an honorable discharge, including for individuals who were discharged prior to the enactment of this bill.

Defund EcoHealth Alliance Act This bill prohibits the award of federal funds to EcoHealth Alliance, Inc (including any subsidiaries or related organizations). This is a nonprofit research organization that studies coronaviruses in bat populations and other environmental health concerns. The Government Accountability Office must also audit federal funds provided to that organization over the past decade. The audit must include the amount of those funds provided by EcoHealth Alliance to China, the Chinese Communist Party, or the Wuhan Institute of Virology.
