Partway through answering questions Sunday during an immigration enforcement blitz in Chicago, a man who appeared to be in federal custody briefly stopped talking when he recognized the man with the Texas accent asking the questions.

Video posted by the former daytime talk-show host Phil McGraw showed him on a ride-along with immigration agents in Chicago on Sunday as authorities stepped up enforcement operations across the United States.

The TV host known as "Dr. Phil" embedded with U.S. immigration enforcement officers during an operation in Chicago on Sunday, defending President Donald Trump's deportation effort as the crackdown neared the end of its first week.
