Ted Cruz announced Wednesday that he will support Marco Rubio's re-election bid.

“Marco is a friend and has been an ally in many battles we have fought together in the Senate," the Texas senator said in a statement. "I'm glad to support him in his bid for re-election."


"Marco is a tremendous communicator and a powerful voice for the American Dream," Cruz continued. "At this time of great challenges, we very much need strong leaders in the Senate who will fight to restore economic growth, to defend our constitutional liberties, and to ensure a strong national security for our nation.”

Rubio announced earlier Wednesday that he had reversed his previous decision and would run for his Senate seat, two days before the filing deadline.
