Colin Powell says he'll be voting for Biden

Former Secretary of State Colin Powell is putting his support behind Joe Biden.

"I'm very close to Joe Biden in a social matter and in a political matter," Powell told CNN's Jake Tapper on "State of the Union" Sunday morning. "I've worked with him for 35, 40 years. And he is now the candidate and I will be voting for him."

But Powell, who served as secretary of State under President George W. Bush, isn't planning on making any campaign trips for the Democratic presidential candidate, just yet.
