His comments come after a source close to Cruz told ABC News and CNN that he was reassessing his endorsement of Trump, amid fierce backlash a video The Washington Post published Friday that showed Trump making lewd comments in 2005 about trying to have sex with married women.

Cruz disavowed the GOP nominee's remarks on Friday, calling them "disturbing and inappropriate." He also questioned the timing of the release of the tape on Sunday, drawing attention to the fact that the network had the tape for years.

But the Texas Republican said on Monday that while he's "articulated at great length" the differences between himself and his former GOP foe, but ultimately lost the party's primary after an increasingly bitter fight.

The controversy comes only weeks after Cruz reversed course and threw his support behind Trump. The Texas Republican had refused to do so months after a primary fight that included Trump insulting Cruz's wife.

Cruz had faced political backlash after refusing to endorse Trump during a speech at the Republican National Convention in Cleveland in July.

While Cruz didn't rule out a future White House run on Monday, he noted that he is focused "right now is on representing 27 million Texans."
