Actor Noah Wyle explains how he and his mom, a nurse for over four decades, are advocating on Capitol Hill for health care workers.

While attempting to mask his rouged mug, Wyle could only laugh and shake his head.

So, Wyle is partnering with FIGS, the medical clothing company, to use the HBO Max show’s popularity as a platform to improve the lives of healthcare workers in this country. This week, Wyle will head to Washington D.

Clooney and Wyle spent several years as fan-favorite characters Doug Ross and John Carter on ER, which ran for 15 seasons between 1994 and 2009. While Clooney left during the fifth season, Wyle was a main cast member through season 11. Both returned for additional episodes throughout the show's run.

George Clooney is sending Noah Wyle his praises for his work on The Pitt. The former ER co-stars have remained friends since working on the NBC medical drama, and while appearing on Late Night with Seth Meyers, Clooney expressed his happiness over Wyle’s success.

Wyle recently reunited with fellow ER alums Julianna Margulies and Anthony Edwards, who played Carol Hathaway and Mark Green, at the opening night of Clooney's Broadway play Good Night, and Good Luck on April 3.

The actor once told THR, “ ‘ER’ is never going to happen again,” but he’s found the closest thing to it with this season’s buzzy show ‘The Pitt.”
