U.S. President Donald Trump's top economic adviser, Larry Kudlow, was "doing well" on Monday night after suffering a "very mild heart attack," a White House spokeswoman said.
"Our Great Larry Kudlow, who has been working so hard on trade and the economy, has just suffered a heart attack," Trump said in a tweet from Singapore shortly before his summit with North Korean leader Kim Jong Un.
White House press secretary Sarah Huckabee Sanders said the 70-year-old Kudlow was "doing well."
