The former U.S. Marine freed from a Russian prison in April said he believes President Joe Biden isn’t doing enough to bring basketball star Brittney Griner or corporate executive Paul Whelan home.

Trevor Reed, who was released in a prisoner exchange for Russian drug trafficker Konstantin Yaroshenko after having served more than two years behind bars, said in an interview that he believes the White House can quickly secure the release of U.S. citizens in Russian prisons and jails.

But he said he's frustrated with the public pace of action on the cases of Griner, a center for the Phoenix Mercury who was arrested this year, and Whelan, who was taken into custody in 2018.

"I can't say 100% what the White House is or is not doing — that's obviously not public information," said Reed, whose full interview will air Tuesday on “Hallie Jackson NOW” at 5 p.m. ET.

"But, in my opinion, the White House has the ability to get them out extremely fast, and they clearly have chosen not to do that. So no, in my opinion, they’re not doing enough.”
