US President Donald Trump on Tuesday (Jun 12) tweeted that his top economic advisor had suffered a heart attack.
Senior White House economic adviser Larry Kudlow speaks during a briefing at the White House in Washington.
A longtime television commentator, Kudlow, 70, was hired by Trump in March to replace Gary Cohn as director of the National Economic Council.
"Our Great Larry Kudlow, who has been working so hard on trade and the economy, has just suffered a heart attack".
Over the weekend, Kudlow waded into a tense back-and-forth between Trump and Canadian Prime Minister Justin Trudeau after the Group of Seven gathering of the world's major industrial nations in Canada's Quebec province.
Kudlow, an unabashed supporter of free trade, joined the Trump administration earlier this year.
Kudlow said the United States had spent the summit negotiating in "good faith" with Trudeau and the other assembled leaders, and that the USA had planned to sign the communique until Trudeau's news conference, which Kudlow called a "sophomoric play".
