Rep. -elect Victoria Spartz, R-Ind., voted for McCarthy previously, but voted "present" during the fourth, fifth, and sixth round of voting. 

In explaining her vote, Spartz said that no Republicans have the votes needed to become House speaker.

"We have a constitutional duty to elect the Speaker of the House, but we have to deliberate further as a Republican conference until we have enough votes and stop wasting everyone's time. None of the Republican candidates have this number yet. That's why I voted present after all votes were cast," Spartz said on Wednesday afternoon.  

On Wednesday evening, Spartz tweeted "Glad to see Kevin McCarthy having meetings with his opposition. We have to resolve it within our conference."
