Trump campaigner Brandon Straka was removed from an American Airlines flight for refusing to wear a mask.
Now, Business Insider reports the airline says he'll be banned for as long as masks are required.
A self-described "former liberal" activist, Straka tweeted about being kicked off the flight after refusing to wear a face covering.
A New York Times reporter who happened to also be on the plane said the flight was held up as Straka argued with flight crew members.
