Multuiple national and international media sources are reporting President Donald Trump's economic Adviser Larry Kudlow has suffered a heart attack.

On Twitter Trump posted:

“Our Great Larry Kudlow, who has been working so hard on trade and the economy, has just suffered a heart attack,” Trump tweeted, just minutes before his highly anticipated summit with North Korean dictator Kim Jong In.

Trump said Kudlow is being treated at Walter Reed Medical Center.

Kudlow joined the president's cabinet in March when he replaced Gary Cohn.
