Like any actor, Noah Wyle prepared for his moment in the spotlight.
The former E.R. star had warned his estranged wife and two children, ages 6 and 9, that he might run into trouble with the police at a Washington D.C. protest this week.
“I think they’re really proud of the old man right now,” Wyle, 40, told the Associated Press Monday while waiting to be processed after his arrest.
The actor, who now stars in TNT’s Falling Skies, was among about 100 protestors taken away in handcuffs during a Capitol Hill protest by the group ADAPT to urge Congress not to cut Medicaid.
