Speaker McCarthy faces triangle of troubles

"I had a plan for this week . It didn't turn out exactly as I had planned," says House Speaker Kevin McCarthy .

McCarthy lacked the votes to even put the defense spending bill on the floor.

McCarthy 's margin is even tighter now thanks to the resignation of former Rep. Chris Stewart , R-Utah.

McCarthy promised that if it will take "a fight, I'll have a fight".

Some conservatives accuse McCarthy of pivoting to impeachment because of struggles to prevent a shutdown and slash spending.

A successful vote to "vacate the chair" would trigger an unprecedented mid-Congress vote for speaker on the floor.

Some Democrats could bail out McCarthy if it comes to that, but top House Democrat says McCarthy could be on his own.
