Speaker Mike Johnson, R-La., told fellow Republican lawmakers that he intends to hold a House-wide vote on whether to impeach Homeland Security Secretary Alejandro Mayorkas "as soon as possible."

Johnson made the announcement in a letter to colleagues sent on Friday, a copy of which was obtained by Fox News Digital.

"The facts show that President Biden and his Homeland Security Secretary Mayorkas have willfully ignored and actively undermined our nation’s immigration laws," the speaker wrote. "Rather than accept accountability, President Biden is now trying to blame Congress for what HE himself intentionally created."

Johnson pointed out polling that showed illegal immigration as an increasingly urgent issue for American voters.

"The American people know better, and that’s why public opinion polls show the country has overwhelmingly sided with us on this issue. When we return next week, by necessity, the House Homeland Security Committee will move forward with Articles of Impeachment against Secretary Mayorkas," he said.

"A vote on the floor will be held as soon as possible thereafter."

He also reaffirmed the House GOP’s support for Texas Gov. Greg Abbott amid a tense standoff with the federal government at the U.S.-Mexico border.

"I made clear that we stand with Texas Governor Greg Abbott in his heroic efforts to protect the citizens of his state and all Americans, and I am emphasizing again today that House Republicans will vigorously oppose any policy proposal from the White House or Senate that would further incentivize illegal aliens to break our laws," Johnson said.
