Senator Mark Warner Mark Robert WarnerFBI director casts doubt on concerns over mail-in voting fraud Democrats call for declassifying election threats after briefing by Trump officials It's time to upgrade benefits MORE (D-Va.), the vice chair of the Senate Select Committee on Intelligence, announced Friday he would introduce an amendment curtailing the president’s ability to revoke security clearances from his critics.

“I will be introducing an amendment next week to block the President from punishing and intimidating his critics by arbitrarily revoking security clearances. Stay tuned,” he tweeted Friday evening.

A Warner spokesperson confirmed to The Hill the amendment would be added to the minibus appropriations bill for the Departments of Defense, Labor, and Health and Human Services. She added that more details would be released Monday.

However, the amendment is likely to be more symbolic than anything else, as its chances of getting it on the government funding bill in the Republican-controlled Senate are slim.

To bring it up to get a vote on the Senate floor as part of the appropriations bill, Warner would need either the consent of every senator or to get Senate Majority Leader Mitch McConnell Addison (Mitch) Mitchell McConnellTrump 'no longer angry' at Romney because of Supreme Court stance On The Money: Anxious Democrats push for vote on COVID-19 aid | Pelosi, Mnuchin ready to restart talks | Weekly jobless claims increase | Senate treads close to shutdown deadline The Hill's Campaign Report: Trump faces backlash after not committing to peaceful transition of power MORE (R-Ky.) or to get Senate Majority Leader Mitch McConnell (R-Ky.) to agree to force a vote.

The amendment comes in response to the White House’s announcement this week it was revoking the security clearance of former CIA Director and frequent Trump critic John Brennan John Owen BrennanJournalism or partisanship?

It also threatened to do the same for nine others, all of whom have either been critical of the president or are connected in some way to the Mueller probe into possible collusion between the Trump campaign and Russia.

Democrats and some Republicans have criticized the move from the Trump administration. House Minority Leader Nancy Pelosi (D-Calif.) called the revocation a “pathetic attempt to silence critics.” Sen. Bob Corker (R-Tenn.) called it "a banana republic kind of thing."
