President Biden was asked by CNN what his message to Russia is following the detainment of Wall Street Journal reporter Evan Gershkovich.
"Let him go," the president said as he departed the White House this morning.
This is the first time Biden has publicly commented on the matter since Gershkovich was accused of espionage by Russian authorities Thursday.
Asked later by another reporter if the US would expel Russian diplomats or journalists over the detention of Gershkovich, Biden said, "That's not the plan right now."
Later on Friday, US Vice President Kamala Harris said she was “deeply concerned” about Gershkovich.
“I will state in unequivocal terms that we will not tolerate and condemn, in fact, repression of journalists and that we are absolutely concerned about any attempt to in any way stifle freedom of the press,” Harris said in a press conference with Zambia’s President Hakainde Hichilema in Lusaka.
