Sen. Mark Warner, D-Va., said Sunday “it is more than bizarre” that President Trump hasn’t condemned Russian President Vladimir Putin since he became president.

Warner’s comments on NBC’s “Meet the Press” on Sunday came a few days after Trump congratulated Putin for his election win despite pleas from his advisers not to do so. Trump did not bring up Russia’s poisoning of a British agent with Putin, or concerns about electoral fraud in the 2016 election.
