WNBA star Brittney Griner didn't want any alone time as soon as she boarded a U.S. government plane that would bring her home.
"I've been in prison for 10 months, listening to the Russians. I want to talk," Griner said, according to Roger Carstens, the special presidential envoy for hostage affairs who helped secure the basketball star's release and brought her back to the U.S. last week.
She then asked Carstens, referring to others on the plane, "But first of all, who are these guys?"
"And she moved right past me and went to every member on that crew, looked them in the eyes, shook their hands and asked about them, got their names, making a personal connection with them,'' Carstens recalled in an interview on CNN's "State of the Union" that aired Sunday. "It was really amazing."
Ultimately, Griner spent about 12 hours of an 18-hour flight talking with others on the plane, Carstens said. The two-time Olympic gold medalist and Phoenix Mercury star spoke about her time in the Russian penal colony and her months in captivity, Carstens recalled, although he declined to go into specific details.
"I was left with the impression this is an intelligent, passionate, compassionate, humble, interesting person, a patriotic person," Carstens said. "But above all, authentic. I hate the fact that I had to meet her in this manner, but I actually felt blessed having had a chance to get to know her."
Griner arrived back on U.S. soil Friday when the plane she was on landed at Joint Base San Antonio-Lackland in Texas.
Although Griner is undergoing a full medical and mental evaluation, Carstens said she appeared "full of energy, looked fantastic."
Griner, who also played pro basketball in Russia, was arrested at Moscow's Sheremetyevo Airport in February after Russian authorities said she was carrying vape canisters with cannabis oil.
The U.S. State Department had declared Griner to be "wrongfully detained" -- a charge that Russia sharply rejected.
President Joe Biden announced Thursday that the U.S. had secured Griner's release. In exchange, the administration offered Russia the release of notorious arms dealer Viktor Bout, who had been serving a 25-year sentence on charges that he conspired to sell tens of millions of dollars in weapons that U.S officials said were to be used against Americans.
But the U.S. was unable to secure the freedom of Paul Whelan, who has been held in Russia for nearly four years. Administration officials have stressed repeatedly that they are still working to release Whelan, whom Russian officials have jailed on espionage charges that both his family and the U.S. government say are baseless.
"They hold Mr. Whelan differently because of these espionage charges," John Kirby, a spokesman for the National Security Council, said Sunday on ABC's "This Week." "So we're working through that now. We are now more informed, clearly having gone through this process over the last few months. We're more informed. We have a better sense of the context here, where the Russians' expectations are, and we're just going to keep working on it."
Carstens, the U.S. government's top hostage negotiator, said "there's always cards" to play in securing an offer for Whelan, and added that he spoke with the jailed American on Friday.
"Here's what I told him. I said, 'Paul, you have the commitment of this president. The president's focused. The secretary of state's focused. I'm certainly focused, and we're going to bring you home,'" Carstens said. "And I reminded him, I said, 'Paul, when you were in the Marines, and I was in the Army, they always reminded you, keep the faith.' And I said, 'Keep the faith. We're coming to get you.'"
