Texas Sen. Ted Cruz says reporters are telling him they have scandalous stories on Donald Trump, but are sitting on them until he becomes the GOP presidential nominee.

That's because the media wants Trump to win the nomination, so he will lose to the expected Democratic nominee, Hillary Clinton, Cruz said Sunday on "Face the Nation." 

Host John Dickerson asked which members of the press were giving him that information, but Cruz declined to answer.

"I'm not going to out media outlets, but I can tell you there is so much there," Cruz said. "When was the last time people are bringing up his tax returns, for example."

"I promise you, come the general election that will be the singular focus of the media," Cruz said. "I think Republicans, we've been burned by that before, we're not interested in losing again, particularly when the stakes, I think, are catastrophic."

Cruz addressed the possibility of a brokered convention, indicating that he would oppose the party coming in with a hand-picked candidate, but didn't directly say he opposed a vote that would put in himself or anyone else already running if a first ballot didn't get anyone the needed 1,237 delegate count required.

The battle in 1976 between Ronald Reagan and Gerald Ford was different, Cruz said, since that was "a battle of the people.

"A lot of people pushing brokered convention in Washington don't want it to be based on the people," he said. "They want to drop in their favorite candidate and try to stifle the will of the people. I think that would be enormous mistake."
