(CBrief) – Republican leader Kevin McCarthy on Thursday continued to work to convince GOP holdouts to vote for him for Speaker, but those efforts proved fruitless by the end of the day. At one point, the California Republican was seen in what appeared to be a heated exchange with one of them, Republican Rep.-elect Andy Ogles of Tennessee.

Fox News reported that C-SPAN cameras caught McCarthy talking to Ogles on the House floor, likely in an attempt to convince the incoming lawmaker to support his bid for Speaker. Ogles has repeatedly voted against McCarthy and looked to remain unconvinced during their discussion.

“As McCarthy and Ogles go back and forth during the tense conversation, McCarthy appears to become increasingly more animated and frustrated. However, what was said during the exchange remains unclear,” the outlet noted, adding:

McCarthy’s irritation comes after falling short in several rounds of voting for House speaker this week. The California Republican lost the ninth round on Thursday after days of tense negotiations failed to sway any holdouts for the embattled lawmaker.

Since Tuesday, McCarthy has been unsuccessful in securing the 218 votes required to become speaker in [ten]separate roll calls.
