Republican presidential candidate Sen. Ted Cruz says he wants to know how many reporters are asking Sen. Marco Rubio (R-FL) when he’s dropping out of the presidential race.

“I’m curious how many reporters ask Marco Rubio, after losing four states in a row: So when do you drop out?” Cruz said at an event in Houston.

Cruz, speaking at his post-caucus party in Nevada Tuesday evening, repeated his pitch that he is the only candidate that can compete with Trump. He noted that he is the only candidate, other than Trump, to win an election so far.

“The only campaign that has beaten Donald Trump…is this campaign,” Cruz said. “There are clear choices in this race,” he added.
