President Biden on Tuesday held his first call since taking office with Vladimir Putin, pressing the Russian president on the arrest of opposition leader Alexey Navalny and the Russia-linked hack on U.S. government agencies, AP reports.

The state of play: Biden also planned to raise arms control, bounties allegedly placed on U.S. troops in Afghanistan and the war in Ukraine, according to White House press secretary Jen Psaki, who said the call took place while she was delivering a press briefing. Psaki added that a full readout will be provided later Tuesday.

Why it matters: Biden is on course for a deeply adversarial relationship with Putin's Russia, but he'll also have to engage with him on critical issues — most urgently, the extension of the New START nuclear treaty, which is due to expire on Feb. 5.
