Sen. Mitt Romney Willard (Mitt) Mitt RomneySenate GOP aims to confirm Trump court pick by Oct. 29: report The Hill's Campaign Report: GOP set to ask SCOTUS to limit mail-in voting Senate GOP sees early Supreme Court vote as political booster shot MORE (R-Utah), who has emerged as a counterweight to Trump in the Senate’s freshman class, announced his support for the resolution Thursday morning, declaring, “This is a vote for the Constitution and for the balance of powers that is at its core.”

His home-state colleague, Lee, who tried to assemble a last-minute deal with the White House to rein in the president’s powers under the National Emergencies Act, said, “The White House is asserting authority to spend money objects and priorities in a manner not themselves directly authorized by Congress.”

“Congress directly refused the request to appropriate the specific amount of funds that we’ere dealing with here,” he added.

The backlash against Trump was all the more pointed after days of lobbying led by Vice President Pence, Homeland Security Secretary Kirstjen Nielsen Kirstjen Michele NielsenDHS IG won't investigate after watchdog said Wolf, Cuccinelli appointments violated law Appeals court sides with Trump over drawdown of immigrant protections Democrats smell blood with new DHS whistleblower complaint MORE and White House legislative liaison Shahira Knight.

Trump himself made a final appeal to Republican senators on Thursday, tweeting about drug smuggling and human trafficking at the border and asserting the constitutionality of his action.

Tillis stated his support for the resolution in a Feb. 25 op-ed in The Washington Post but since then has come under pressure from conservatives in North Carolina, who warn he may face a primary challenge in 2020.

Sasse was seen as a possible "yes" vote, but he too is on the ballot in 2020 and could face a primary challenger on the basis of his up-and-down relationship with Trump.

Rubio, however, a member of the Senate Appropriations subcommittee on military construction, made clear last month that he had serious misgivings about diverting funds Congress had appropriated to rebuild and maintain military installations.

Some Republicans who voted against the resolution flew under the radar in the days leading up to the vote.

Jerry Moran Gerald (Jerry) MoranLobbying world This World Suicide Prevention Day, let's recommit to protecting the lives of our veterans Hillicon Valley: Zuckerberg acknowledges failure to take down Kenosha military group despite warnings | Election officials push back against concerns over mail-in voting, drop boxes MORE (R-Kan.), who kept his position private and didn’t participate prominently in the frantic negotiations of the past week to come up with a way to defeat the disapproval resolution, announced his "yes" vote on Thursday morning.

“I share President Trump’s goal of securing our borders, but expanding the powers of the presidency beyond its constitutional limits is something I cannot support,” he tweeted.

After years of watching power in Washington slowly shift from Congress to the White House, a trend accelerated by the gridlock that has characterized Capitol Hill over much of the last decade, Republican senators on Thursday said they hah had enough.

In the end, the vote boiled down to an effort by GOP lawmakers to preserve their power of the purse, even though they agree with Trump’s desire to secure the border to halt the flow of drugs and illegal immigrants.

“One branch of government is asking another branch to give up power. Nobody gives up power around here. People want power, they don’t want to give it up,” said Sen. John Kennedy John Neely KennedyMORE (R-La.), explaining why it was perhaps inevitable that Republican colleagues would rebel against Trump’s emergency declaration.

Thursday’s vote was the second time in two days the Senate voted to limit Trump’s power.

Senators voted Wednesday 54-46 to withdraw U.S. military support for a Saudi-backed coalition fighting in Yemen’s civil war. Seven Republicans voted for that measure even though it faces a veto.

Here is the list of the GOP senators who voted against Trump on the emergency declaration:

Sen. Lamar Alexander (Tenn.)

Sen. Roy Blunt (Mo.)

Sen. Susan Collins (Maine)

Sen. Mike Lee (Utah)

Sen. Jerry Moran (Kan.)

Sen. Lisa Murkowski (Alaska)

Sen. Rand Paul (Ky.)

Sen. Rob Portman (Ohio)

Sen. Mitt Romney (Utah)

Sen. Marco Rubio (Fla.)

Sen. Pat Toomey (Pa.)

Sen. Roger Wicker (Miss.)
