Aides to Democrats on the House Foreign Affairs Committee put the possible size of the package at roughly $15 billion, the newspaper reported, citing sources. Backers of Kyiv aim to pass part of the measures before January, when the new Congress is seated.
One priority is aid to Ukraine's energy sector, which Russia has been attacking ahead of winter, a Democratic Party representative on the committee told the FT.
The vehicle could be the annual National Defense Authorization Act (NDAA), which must be passed before the current session ends. Melinda Haring, a senior adviser at Razom for Ukraine, told the FT that amendments to it could cover sanctions, intelligence support, interceptor missiles, and Starlink and Starfield.
Separately, lawmakers want to amend the sanctions law targeting Russia's defense and energy sectors, named after the late Republican senator Lindsey Graham. In October, Trump used his exemption authority to lift restrictions on Moscow after an agreement with Vladimir Putin on diesel fuel supplies.
"We will fix the Graham law," one aide to Democrats on the House Foreign Affairs Committee told the FT, adding that a year and a half had gone into trying to impose sanctions, after which they were abandoned.
According to the FT, the Senate Foreign Relations Committee has already demanded that Elon Musk preserve all documents related to the slowdown of Starlink in October, which the newspaper says hampered Ukraine's ability to repel Russian attacks. The committee is also preparing requests to ports, banks and other participants in the diesel deal.
Another line of inquiry is an examination of the commercial interests of Steve Witkoff, Trump's special envoy for talks on Ukraine, and of the president's son-in-law Jared Kushner, who represents Trump in negotiations on Iran. The White House said the administration is focused on ending the war and will respond to legitimate requests from Congress.
Oleksandr Merezhko, head of the Verkhovna Rada committee on foreign policy, said he does not expect radical changes, since foreign policy remains the prerogative of the US president. According to him, the main thing is to avoid further lifting of sanctions on Russia and new deals between Washington and Moscow.
Democrats do not have the two-thirds majority in both chambers needed to override a presidential veto. According to Reuters sources, they may count on support from Republicans who previously backed continued arms supplies to the Ukrainian armed forces, though many of those who supported Kyiv will not be in the new session.
