Security is tight at the Denver federal court for the start of a civil case pitting Taylor Swift against a former disc jockey she accuses of groping her. Police and a bomb-sniffing dog waited in the rain Monday (Aug. 7) with about a dozen reporters before potential jurors were set to arrive for questioning. 

David Mueller has sued Swift, saying he lost his job after she falsely accused him of grabbing her backstage before a 2013 concert. He's seeking $3 million from the pop superstar. Swift is countersuing, claiming sexual assault. She says she wants to hold Mueller accountable and is seeking $1.

Swift doesn't have to be in court for jury selection, which is expected to end Tuesday. But she does have to be present for the rest of the trial and is expected to testify.

Members of the public can line up to watch proceedings from an overflow room in the courthouse, but so far there hasn't been a big turnout.
