Senator Chuck Schumer, a Democrat from New York, introduced a motion to block former President Donald Trump from establishing a compensation fund.
The measure targets Trump’s ability to create a fund that could be used to pay out settlements or judgments.
A handful of Republican senators have indicated they would support the motion.
The motion requires only 50 votes to pass in the evenly divided Senate.
Supporters argue the fund could be used to evade personal financial accountability.
Opponents view the motion as a political maneuver against Trump’s private business interests.
The Senate is expected to vote on the measure later this week.
The outcome remains uncertain as both parties negotiate ahead of the vote.
