Marjorie Taylor Greene threatens to force an impeachment vote for Joe Biden over his mishandling of the southern border

Rep. Marjorie Taylor Greene has threatened to force a vote to impeach President Joe Biden this week over his border policies - prompting another headache for Speaker Mike Johnson.

Johnson distanced himself from the effort - and emphasized that impeachment needs to move through the probe led by the Oversight, Judiciary and Ways and Means Committees. 

'I think President Biden is the worst president in the history of the country,' said Johnson. 'There may well be impeachable offenses. There's an investigation process.' 

After first threatening the resolution on social media, Greene seemed resolute in calling it up for a vote after leaving an all-GOP conference meeting on Tuesday. 

Asked what it would take for her to hold off on bringing forth an impeachment resolution, she replied: 'Impeachment.' 

Johnson noted that the House already impeached Homeland Security Sec. Alejandro Mayorkas over his handling of the southern border. 'Historically desperate times call for historic measures. It's a very rare thing to impeach a cabinet official, but we had to do it. 

Last month Greene forced a vote on a motion to vacate Mike Johnson from the speakership that went down in failure.  

Greene said Johnson is 'all talk,' and asked 'what's the point' of passing party-line legislation that dies in the Democratic-led Senate and at the president's desk. 

'That means nothing. That's how people see it ... and Speaker Johnson's going to have to figure it out.' 

'He needs to shut down the government over these things, use the power of the purse. I don't know that he's willing to do that, it's more talk.' 

Greene even said Republicans should not be wasting time on 12 separate appropriations bills to fund the government in 2025 - a pivotal demand from most hard-right lawmakers who detest the 'omnibus' process that rolls funding for all agencies of government into one bill at the last minute. 

'Republicans wanna be up here like "oh we're passing our 12 separate appropriation bills" that are going nowhere, by the way,' she said. Once the House passes their appropriations bills, they must be negotiated with the Senate's versions.

'Biden already said he's gonna veto this one, MIL-CON, what a waste of time,' she said, referencing the upcoming House vote on the funding bill for military construction and veteran's affairs. 

But impeaching Biden in the House would also go nowhere - the Senate would not vote to convict the president. 

The threat comes as President Biden on Tuesday afternoon will roll out a new executive order that's expected to cap asylum claims at 2,500 per day. 

Over 350,000 migrants who entered the U.S. illegally have had their asylum court cases dismissed, allowing them to go free without a verdict on the merits of their entry, a bombshell new report indicates.
