Allies of President TrumpDonald John TrumpGraham: America must 'accept the pain that comes in standing up to China' Weld 'thrilled' more Republicans are challenging Trump New data challenges Trump's economic narrative MORE are celebrating the Supreme Court's ruling Friday allowing the Trump administration to start using military funds to construct a border wall.

The ruling, which put on hold a lower court decision that at least temporarily halted the use of $2.5 billion in reallocated funds, allows the administration to start using the money.

Conservative commentators and groups allied with the president praised the ruling, which marked a major victory for the administration and the president's border agenda.

Charlie Kirk, founder of conservative youth organization Turning Point USA, also celebrated the decision, calling it "a massive win for our country and for the President."

And Republican National Committee Chairwoman Ronna Romney McDaniel took a victory lap on the court ruling, tweeting, "Getting good judges on the bench matters."

"It's a major step forward in securing our border and keeping our country safe," Brian Kolfage, founder of WeBuildTheWall, a group behind a crowdfunded effort to build a wall along the U.S.-Mexico border, said in a statement to The Hill on Saturday.

Kolfage announced the Supreme Court's decision to supporters gathered for the organization's Symposium at the Wall conference on Friday, drawing cheers from those in the audience.

"There's a lot of work yet to be done, and I'm glad that the organization along with private citizens are helping to achieve that," Kolfage told The Hill.

After a record 35-day partial government shutdown over border wall funding earlier this year, Trump declared a national emergency at the border and ordered roughly $6 billion in military funding be diverted to build a wall, a move that has since been challenged in court. Friday's ruling allows the administration to go ahead and use $2.5 billion in military funds.

For many Trump supporters, the Supreme Court's decision Friday — which was released unsigned by the court and which the court's four liberal justices each at least partially dissented to — marked the fulfilling of a major campaign promise from the president, despite opponents signaling that they will continue to challenge it in court.

“Any reasonable person would acknowledge that Donald Trump’s election as President of the United States in 2016 was a mandate to build the wall, uphold the integrity of our borders and defend the sovereignty of our nation," Jenny Beth Martin, head of the activist group Tea Party Patriots Action, said in a statement.

Conservative radio personality Hugh Hewitt similarly wrote on Twitter that the wall "is finally going to get built."

"It isn’t a full answer but part of the answer: the visible expression of an invisible commitment to border security," he wrote. 

Trump himself called the ruling "a Big WIN for Border Security and the Rule of Law!" in a Friday tweet.

Democrats and those suing to block the administration from using the funds to build the wall blasted the ruling Friday, arguing that it undermined the separation of powers in the federal government since lawmakers have authority to appropriate funding.

“Border communities, the environment, and our Constitution’s separation of powers will be permanently harmed should Trump get away with pillaging military funds for a xenophobic border wall Congress denied,” American Civil Liberties Union attorney Dror Ladin said in a statement, adding that court challengers will ask to expedite the appeals process.
