Rubio says he is not interested in VP run with Trump

Former Republican hopeful Marco Rubio is making it abundantly clear that he's not at all interested in being Donald Trump's vice presidential running mate.

In a Facebook post Monday, Rubio writes, "I have never sought, will not seek and do not want to be considered for Vice President."

Rubio, who bowed out the presidential race on March 15 after being routed by Donald Trump in the Florida primary, says he's focused on his job in the Senate.

Rubio says Trump "will be best served by a running mate and by surrogates who fully embrace his campaign."

He adds, "While Republican voters have chosen Donald Trump as the presumptive GOP nominee, my previously stated reservations about his campaign and concerns with many of his policies remain unchanged."

Another former Republican hopeful, Ted Cruz, may have shut down his presidential bid, but a top adviser still hopes to push his conservative agenda at the Republican national convention - perhaps over bathroom use by transgender people.

In an email to convention delegates backing the Texas GOP senator, Cruz adviser Ken Cuccinelli says those at the July gathering in Cleveland will have a chance "to strengthen and protect the conservative elements" of the party's platform - a statement of the party's policy goals that does not bind the presidential nominee.

The 2,472 GOP delegates will have final say on the party's rules and platform at the convention. Billionaire Donald Trump is the GOP's presumptive nominee.

Cuccinelli said in the interview that he expected a push for a statement in the platform effectively saying: "Boys should only be allowed to go in the boys' bathroom, and girls should only be allowed to go in the girls' bathroom."

The federal Justice Department sued North Carolina on Monday over the state's law requiring transgender people to use the restroom of the gender on their birth certificate.

The email, which invited Cruz backers to join a Monday night conference call on the subject, was first reported by The New York Times.
