This much we know: U.S. Sen. Ted Cruz of Texas met with President-elect Donald Trump at Trump Tower in New York on Tuesday.

According to a report in Bloomberg, the former bitter rivals talked about the possibility of Cruz serving as attorney general in a Trump administration. Bloomberg cited an unnamed "person familiar with the matter."

U.S. Sen. Lindsey Graham, R-S.C., a former rival of both Trump and Cruz in the GOP presidential race, has also suggested in recent days that Trump should consider putting Cruz on the Supreme Court to fill the vacancy created by the death of Justice Antonin Scalia.

Catherine Frazier, who speaks for Cruz on political matters, had this to say Tuesday:

“Sen. Cruz is pleased to have the opportunity to meet with President-elect Trump in New York today. The American people issued a clear mandate to ‘drain the swamp’ in Washington, repeal Obamacare and start over with cost-effective, patient-centered health care reform, appoint constitutionalist judges to the Supreme Court, secure our southern border and enforce immigration laws, and enact policies that will create more good-paying jobs for the American people. On behalf of the 27 million Texans he represents, the senator looks forward to assisting the Trump Administration in achieving these objectives.”

Cruz was Trump’s most serious rival for the Republican nomination. Trump routinely referred to Cruz as “Lyin’ Ted.” On the day Cruz left the race, he described Trump as a “pathological liar.” Cruz didn’t endorse Trump until September, at the urging of Lt. Gov. Dan Patrick, who chaired first the Cruz campaign in Texas and then the Trump campaign in the state, and said he didn’t want Cruz on the outside looking in if Trump were elected.

Graham, who joked in February that “if you killed Ted Cruz on the floor of the Senate, and the trial was in the Senate, nobody would convict you,” ultimately backed Cruz over Trump.

Cruz served as Texas solicitor general under Attorney General Greg Abbott, who is now governor.
