Republican Representative Joe Wilson of South Carolina after collapsing in hospital

Longtime Rep. Joe Wilson, R-S.C., was hospitalized for treatment Tuesday night after collapsing at an event in Washington, according to a congressional aide familiar with the situation.

Later Tuesday evening, Wilson's office confirmed the news about X.

“Congressman Joe Wilson (R-SC) has become ill and is being evaluated at a local hospital in Washington, DC,” it said.

His son, South Carolina Attorney General Alan Wilson, later posted on behalf of his hospitalized mother: “Doctors have confirmed that he had stroke-like symptoms.”

The younger Wilson said he was able to speak to his father by phone, adding that the congressman was “stable and being monitored by medical professionals.”

Rep. Wilson, 77, a ranking member of the Foreign Affairs Committee, was present for two series of votes in the House on Tuesday afternoon and joked with reporters just outside the chamber.

He said Tuesday that he had had a busy summer recess; Congress only returned this week from a month-long recess.

Wilson told reporters he had just returned from an eventful trip to the Philippines, Australia and Europe, where he met with NATO Secretary General Jens Stoltenberg, among others, before campaigning in his native South Carolina.

NewsNation first reported on Wilson's hospitalization.

Wilson, who has represented a conservative district in central and southwestern South Carolina since 2001, is perhaps best known for shouting “You're lying!” at President Barack Obama during a joint session of Congress in 2009 after he said illegal immigrants would not receive benefits under the law that eventually became the Affordable Care Act.

Wilson was reprimanded by the entire House of Representatives and apologized to Obama.

More recently, he has become known as one of Ukraine's staunchest supporters in the war against Russia and often wears badges or flags in blue and yellow, the national colors of Ukraine.
