On Friday President Trump plans to sign the bipartisan omnibus spending bill presented by Congress to keep the federal government funded. However, since the legislation does not provide all the billions of dollars he needs to fund his wall at the U.S.-Mexico border, he will also declare a national emergency. He has reportedly found $8 billion from different government agencies to get the job done.

The emergency declaration has the blessing of some Republican lawmakers, like Sen. Lindsey Graham (R-SC).

But, plenty others have let the president know they do not approve of his executive decision. One of its most vocal critics is Sen. Marco Rubio (R-FL).

"We have a crisis at our southern border, but no crisis justifies violating the Constitution,” Rubio wrote in a statement on Thursday. He argued that a future Democratic president could use the same strategy to enforce something like the progressive Green New Deal.

He wasn't the only Republican senator to question Trump's presidential privileges here.

Sen. Susan Collins (R-ME) has also noted that Trump's emergency declaration is of "dubious constitutionality.”

President Trump will speak about the national emergency shortly from the White House.
