The mother of Sgt. Andrew Tahmooressi, a U.S. Marine jailed in Mexico, is speaking out before a hearing in Washington Wednesday to discuss his case.
"We’re hoping to build momentum,” Jill Tahmooressi told CNN's Michaela Pereira.
Jill will be testifying at the hearing tomorrow, along with talk-show host Montel Williams.
Andrew Tahmooressi has spent the last six months in a Tecate, Mexico, prison on a weapons charge.
He was arrested at a checkpoint in Tijuana, Mexico, after Mexican customs agents found three firearms in his truck, including a .45-caliber pistol, a pump shotgun and an AR-15 rifle.
The Marine reservist's mother said they have had four hearings in Mexico on his case so far, but she was still awaiting the results of a court report on his mental health at the time of the interview.
“At least there are quite a few dots that are connected so I am feeling more optimistic,” Jill Tahmooressi said.
