Republican House of Representatives Speaker Paul Ryan announced on Tuesday that he will not be running for US President.

Ryan told WISN radio that "I am going to try again today to put this bed. The answer is 'No' and my strong opinion is, if it goes to an open convention ... my answer is the delegates should pick among the people who actually ran for president this year..."

"I made a really clear choice not to run for president. Therefore, I will not be nominated. I will not allow my name to be placed in nomination and it will not be me. ...I just want to be really crystal clear," he said.
