House Homeland Security Committee Chairman Michael McCaul said he has cautioned Donald Trump on his words and relationship with Russian President Vladimir Putin.

“I spoke with him yesterday. I urged caution when it comes to this man,” the Texas Republican said on MSNBC. “I think he respects him in terms of his strength, being a strong man. I think Mr. Trump envisions himself in that light as well, but urged caution to not think that we can embrace him. Mr. Putin is not our friend.”
