FILE - In this July 16, 2018, file photo, U.S. President Donald Trump, left, and Russian President Vladimir Putin shake hands in Helsinki, Finland. President Joe Biden may feel an incentive to secure Wall Street Journal reporter Evan Gershkovich's release because of boasts by Trump, who is his main challenger in this year's election, that he can easily get the journalist freed. The Kremlin says it has not been in touch with Trump. (AP Photo/Pablo Martinez Monsivais, File)
