Sen. Mitt Romney (R-Utah) plans to vote to block Trump's border emergency declaration at Thursday's Senate hearing, per CNN.
The bottom line: With Romney's vote, there is enough GOP support for the Senate's resolution against Trump's emergency declaration to pass. But Trump made it clear again on Thursday that he will veto the bill if necessary. It would be the first veto of his presidency, and made as Republicans voice concerns about executive overreach.
Where they stand: Sens. Susan Collins (R-Maine), Lisa Murkowski (R-Ak.) and Thom Tillis (R-N.C.) said in February they would also vote in favor of the resolution, and only 4 GOP votes are needed.
