Despite his record-busting 11 failed speaker votes looming large, McCarthy entered the Capitol this morning showing confidence.

Peppered with questions about whether his recent offer to Republican hardliners who oppose him would be enough to secure his gavel, McCarthy said he wasn't sure if today would yet be the day, but said, "We're going to make progress," adding, "We are going to shock you."

But he also noted that there will likely be member attendance issues Friday and over the weekend as some lawmakers have already left in Washington.

"I don't know if we can get there today, but we're going to make progress," McCarthy said.

During a conference call this morning with the Republican conference, McCarthy told members that there's not officially a deal to vote him speaker, but said he believes they're "in a good position" and working in "good faith."

"I'm not telling you we have an agreement," McCarthy said on the call, according to multiple sources. "We're in a good position and having meetings."

McCarthy ally, Patrick McHenry, said on the call that no gavels for committee chairmanships have been promised during their talks.

McCarthy, again, said on this call that he has agreed to offer a key concession: making it even easier to remove him as speaker if he is elected. So, a single member, from either party, can trigger an up-or-down simple majority vote on whether to remove the speaker.

But still, after failing 11 times, the math still doesn't appear to be in McCarthy's favor. And there could be votes over the weekend.

Rep. Brian Fitzpatrick, a pro-McCarthy ally, told ABC News that the next phase of working on the handful of hard no's will involve more isolated discussions with those who have concerns beyond just personal issues.

"It's not a monolithic group. Each one of them have different concerns. Some, it's motion to vacate, some, it's guardrails around the budget. But when you shrink that group down, you're able to have one-on-one conversations as to what does it take for them to get to yes, if anything," Fitzpatrick said.

The vast majority of the Republicans blocking McCarthy's speaker bid have given life to the so-called 'big lie' in the two years since the Capitol attack.

Of the 15 incumbents in the flank rejecting McCarthy, 14 challenged the results of the 2020 election two years ago.

Just two of the 20, which includes five freshmen, acknowledge the legitimacy of the 2020 election: Chip Roy of Texas and Rep.-elect Josh Brecheen of Oklahoma.

The small but significant group appears on the verge now of taking the reins of power in Washington by using their leverage against McCarthy, who himself has a tortured relationship with Jan. 6 and the 2020 election.

McCarthy was one of 147 House Republicans to reject its certification ahead of a floor speech deeming Trump "bears responsibility" for the "mob attack."

With all other House business put on hold, Republican Rep. Don Bacon of Nebraska has continued to voice frustration with the small but significant flank of his party refusing to support McCarthy's speaker bid.

"Our constituents call me and they want help with passports, visas, disability claims with the VA, and all that's on hold -- and that's because of these 20 people who are holding us hostage," Bacon told ABC News Congressional Correspondent Rachel Scott.

Bacon, who serves on the House Committee on Agriculture and House Committee on Armed Services, said he was also forced to cancel a classified briefing this week because he lost his security clearance.
