Donald Trump responds to his son being subpoenaed

"I was very surprised. I saw Burr saying there was no collusion two or three weeks ago. I was very surprised to see my son -- my son is a good person, he works hard. The last thing he needs is Washington, D.C. He’d rather not be involved," the president said.

"My son is a good person. He testified for hours and hours. My son was totally exonerated by Mueller who doesn’t like Trump, me. And for my son, after being exonerated to now get a subpoena to speak again after telling everyone about a nothing meeting, I’m pretty surprised."
