Attorney General Jeff Sessions had two conversations with the Russian ambassador to the United States during the presidential campaign season last year, contact that immediately fueled calls for him to recuse himself from a Justice Department investigation into Russian interference in the election.

Sessions, an early supporter of President Donald Trump and a policy adviser to the Republican candidate, did not disclose those communications at his confirmation hearing in January when asked what he would do if "anyone affiliated" with the campaign had been in contact with the Russian government.
