Trump says friend and economic advisor Larry Kudlow has suffered a heart attack

President Donald Trump tweeted Monday that his economic advisor Larry Kudlow has suffered a heart attack.

"Our Great Larry Kudlow, who has been working so hard on trade and the economy, has just suffered a heart attack. He is now in Walter Reed Medical Center," Trump tweeted late Monday.

There was no additional information from the White House or second source, rather it was only Trump's twitter account.

UPDATE:

“Earlier today National Economic Council Director and Assistant to the President Larry Kudlow, experienced what his doctors say, was a very mild heart attack," White House press secretary Sarah Huckabee Sanders said in a statement released late Monday. "Larry is currently in good condition at Walter Reed National Military Medical Center and his doctors expect he will make a full and speedy recovery. The President and his Administration send their thoughts and prayers to Larry and his family."
