(CNN) – Four senators were trapped in a Senate subway car Tuesday morning in Washington, according to tweets from Missouri Sen. Claire McCaskill.
"Stuck in a tram from Capitol to Hart. Broken. Not moving. Lieberman and Alexander in next car. And Voiniitch.[sic] Wonder how long we'll be here?" Sen. Claire McCaskill wrote on her Twitter page.
Lawmakers often use the Senate subway to commute between the Capitol and their offices.
According to recent tweets, McCaskill and her colleagues have since been rescued. The Democratic senator from Missouri is poised to return to the Capitol for a vote - but as for riding the subway back, McCaskill says: "Takes longer, but I think I'll walk."
