Ty Cobb, in his first interview since joining the team representing President Donald Trump related to the Russia investigation, explained why he agreed to work with the president and what he expects to do.

“My dad was a Navy fighter pilot and I grew up in rural Kansas,” Cobb said as he boarded a flight for his Charleston, South Carolina, home on Friday. “If the president asks you, you don’t say no. I have rocks in my head and steel balls.”
