Sens. Susan Collins (R-ME) and Dan Sullivan (R-AK) sided with Democrats on a string of affordability votes in an overnight “vote-a-rama” session, undercutting GOP messaging even as they backed the party’s immigration funding bill.

Facing competitive reelection races this fall, Collins and Sullivan sided with Democrats on amendments to lower the cost of groceries, energy, healthcare, and prescription drugs, as well as to boost school meal programs and food stamps. Still, both supported final passage of the measure that advances new money for immigration enforcement.
