The bill also allows for an abatement and refund of additional taxes, interest, and penalties assessed to such individuals for failing to meet a federal tax deadline during a period of detention.
Specifically, under the bill, the time period during which a U.S. national is unlawfully or wrongfully detained abroad or held hostage abroad is disregarded in determining certain federal tax deadlines, including deadlines for
• filing a return for and paying federal income, estate, gift, employment, or excise taxes;
• a tax credit or refund claim; and
• the determination, assessment, and collection of additional taxes, interest, or penalties.
The bill requires the Department of State and the Department of Justice to annually provide the Internal Revenue Service (IRS) with lists to identify U.S. nationals who qualify for an extension.
The bill also requires the IRS to (1) abate and refund additional taxes, interest, and penalties assessed for any tax year ending during a period of detention for which an extension of a federal tax deadline is permitted; and (2) establish a program allowing U.S. nationals unlawfully or wrongfully detained abroad or taken hostage abroad (or their spouse or dependent) to claim a refund of additional taxes, interest, and penalties assessed for any tax year ending during a period of detention from 2021 to the bill’s enactment date.

This bill expands the Animal and Plant Health Inspection Service (APHIS) producer indemnity and compensation program to include compensation for all poultry growers and layers located in an APHIS-determined control area, which may include non-infected poultry.
Currently, APHIS provides indemnity and compensation to producers to remove animals classified as affected, suspect, or exposed to diseases of concern, including highly pathogenic avian influenza (HPAI). An APHIS-determined control area consists of both an infected zone and a buffer zone. Under the bill, APHIS must compensate all owners of poultry growing or laying facilities within a control area, which may include facilities that are located in the buffer zones and have non-infected poultry.
Further, the bill establishes a new compensation payment formula that requires payments to be based on the owner’s average income from the five most recent flocks.
A joint resolution terminating the national emergency declared with respect to energy.
Sponsor Timothy Kaine (D). Joined Feb 11, 2025. 11 cosponsors. S.J.Res. 10 on Congress.gov(opens in a new tab)
Introduced
This joint resolution terminates the national emergency relating to energy declared by the President on January 20, 2025, in Executive Order 14156.
The executive order states that the supply of and infrastructure for energy in the United States is insufficient to meet the country's needs. It defines energy as crude oil, natural gas, lease condensates, natural gas liquids, refined petroleum products, uranium, coal, biofuels, geothermal heat, the kinetic movement of flowing water, and critical minerals.
The executive order directs the heads of executive departments and agencies to use available emergency and other authorities to take certain actions to address this topic, including approving development of domestic energy resources, expediting the completion of authorized energy infrastructure (particularly in the Northeast, West Coast, and Alaska), and pursuing the use of emergency permitting provisions under certain environmental regulations.
The executive order also directs the Department of Defense to conduct an assessment of its ability to acquire and transport energy resources (particularly in the Northeast and West Coast), and invokes emergency military construction authority to address any vulnerabilities identified in the assessment.

Introduced
Carried Interest Fairness Act of 2025
This bill taxes income from carried interest at ordinary income tax rates and makes other changes related to carried interest. (Some exceptions apply.)
As background, a general partner in a private equity firm or hedge fund (typically structured as a partnership) generally receives a share of the profits from the assets managed by the general partner (known as carried interest). Under current law, carried interest is characterized (for federal tax purposes) as an interest in a partnership’s capital and, thus, taxed at capital gains tax rates (which may be lower than the applicable ordinary income tax rates).
Under the bill, net capital gain and loss attributable to carried interest is recharacterized as ordinary income and loss and, thus, taxed at ordinary income tax rates. (Some exceptions apply.)
The bill also treats as ordinary the money (or fair market value of property) received by a partner in a sale or exchange of carried interest. (Thus, the bill extends what is known as the hot asset rule to include carried interest.)
Further, the bill deems distributions of carried interest by a partnership in exchange for interest in other partnership property a sale or exchange of such property and, thus, requires the partner to recognize ordinary gain on the distributed carried interest.
Finally, the bill imposes self-employment taxes on carried interest income.

Additionally, the Department of Defense may not terminate the payment of an annuity for a surviving spouse under the Survivor Benefit Plan solely because the surviving spouse remarries.
The bill also expands the definition of a dependent under TRICARE to include a remarried widow or widower whose subsequent marriage has ended due to death, divorce, or annulment.
