Trump's chief adviser Kudlow 'doing well' after heart attack: White House

President Donald Trump’s top economic adviser, Larry Kudlow, was "doing well" on Monday night after suffering a 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 Kim Jong Un. “He is now in Walter Reed Medical Center.”

Trump offered no further details on the 70-year-old Kudlow’s medical condition or prognosis.

White House Press Secretary Sarah Huckabee Sanders later said of Kudlow: "he’s doing well."

Kudlow’s wife, Judy, said he was doing “fine,” Robert Costa, a Washington Post reporter, said in a Twitter posting. In another tweet, Costa said Kudlow “is up and talking tonight and spoke by phone with Dr. Art Laffer,” citing two people close to Kudlow
