President Trump has tweeted that his top economic advisor, Larry Kudlow, 70, had a heart attack and is in the hospital. The White House later said he's expected to make a full recovery.
The backdrop: Kudlow, a veteran of the Reagan administration who rose to prominence as a cable TV host and commentator, joined the Trump administration in March. He sharply defended Trump in an interview with CNN on Sunday, saying Canadian Prime Minister Justin Trudeau had "stabbed [the United States] in the back" with his comments following the G7 summit. Trump's tweet came just minutes before he was set to meet with North Korea's Kim Jong-un.
