President Trump dropped a bomb on Twitter right before his meeting with North Korean leader Kim Jong Un: that his top White House economic adviser Larry Kudlow suffered a heart attack and was being treated at Walter Reed Medical Center.
The Washington Post's Robert Costa reports that friends of Kudlow learned about his heart attack via Twitter, and began "rushing to the hospital, trying to reach his wife, Judy." The White House did not release any information on his condition, and rumors began to swirl, before Costa was able to reach Judy Kudlow. She told him that her husband is "doing fine. Doctors here are fabulous."
Two people close to Kudlow later told Costa he's "up and talking tonight" and has been making phone calls with doctors. Kudlow, 70, became the director of the National Economic Council earlier this year, and on Sunday, made waves when he accused Canadian Prime Minister Justin Trudeau of "stab[bing] us in the back" by undermining Trump ahead of his talks with Kim.
UPDATE 10:32 p.m. ET: White House press secretary Sarah Huckabee Sanders released more information on Kudlow's condition, saying that his doctors are describing his heart attack as being "very mild."
