For the first time, Tennessee U.S. Senator Bob Corker appeared with Donald Trump at a rally in Raleigh, North Carolina on Tuesday.

Trump introduced Corker from the podium, and stood by his side while Corker made some brief comments.

CNN is reporting that Corker is on Trump's short list for a possible running mate.

Corker has praised Trump on some occasions, and given him criticisms on other occasions. Appearing from the NewsChannel 9 studios on ABC's 'This Week' last month, he said that Trump is going to have to change his strategy he used to win the GOP primaries as he approaches the general election.
