Citing a leaked private conversation between House Speaker Paul Ryan and House Republicans that was published by Breitbart News on Monday, Fox Business Network host Lou Dobbs has called on Ryan to resign.

Dobbs, who hosts "Lou Dobbs Tonight" on FBN, took to Twitter on Tuesday morning to call for Ryan's resignation, after a pre-election recording of Ryan surfaced in which the House Speaker tells GOP colleagues that he will never support Donald Trump.

In the audiotape, which was recorded on Oct. 10 of last year, Ryan can be heard promising Republican lawmakers: “There are basically two things that I want to make really clear, as for myself as your Speaker.

I am not going to defend Donald Trump—not now, not in the future."

Lou Dobbs is no fan of Paul Ryan

Dobbs tweeted the link to the Breitbart story on Tuesday morning, adding, simply: "Ryan Should Resign." He then issued a series of tweets calling for the full repeal of Obamacare, describing the Republican replacement bill as a failure.

The GOP replacement bill, referred to as "RyanCare" by some Republicans, has been skewered by lawmakers from both parties. The bill will be voted on by the House Budget Committee on Thursday, where many suspect that it will die on the table.

Four Republicans would have join Democrats in voting against the bill on Thursday in order to kill it, and the makeup of the Budget Committee suggests that this is a very likely possibility.

Freedom Caucus members hold the fate of RyanCare in their hands

Three members of the House Budget Committee are members of the ultra-conservative Freedom Caucus.

So far at least one of these members, Dave Brat of Virginia, has stated his intention to vote against the replacement bill.

So far, seven Republican members of the House Budget Committee have indicated that they would settle for nothing less than a full repeal of Obama's Affordable Care Act. At least two of them -- Sen. Rand Paul of Kentucky and Sen.

Mark Sanford of South Carolina -- have publicly bashed the GOP replacement bill championed by Paul Ryan.
