GOP speaker fight is 'probably one of the most embarrassing things I've seen': McCaul

House Foreign Affairs Committee Chairman Michael McCaul on Sunday bemoaned the nearly three weeks -- and counting -- that the chamber has gone without a speaker amid conservative infighting over how to fill the key leadership role.

"This is probably one of the most embarrassing things I've seen, because if we don't have a speaker of the House, we can't govern," McCaul, a 10-term Republican lawmaker from Texas, told ABC "This Week" co-anchor Jonathan Karl.

The crisis in the House is unfolding at a time of growing conflicts abroad -- in Europe, where Ukraine is seeking to repel Russia's invasion, and in the Middle East, where Israel is fighting Hamas in the wake of a terror attack that killed more than 1,400.

"The world's on fire. This is so dangerous what we're doing," McCaul said of the paralysis over choosing a speaker.

"We have very important issues right now, war and peace, and we cannot deal with an aid package, or my resolution condemning Hamas and supporting Israel. We can't do that," he said.
