The Daily Beast reports:
Multiple sources in and out of the West Wing say that some of Trump’s closest advisers have recommended that he not criticize Moore publicly prior to the election in November.
Among those privately encouraging him to stay mum have been Kellyanne Conway, the president’s counselor and former campaign manager, and Steve Bannon, Trump’s former chief strategist and current Breitbart chairman.
According to two sources—one a White House official and the other a Republican source close to both the White House and Bannon—Bannon has spoken multiple times on the phone to President Trump since late last week. At least one of those calls was devoted to discouraging the president from rejecting or criticizing Moore in public statements.
According to the above-linked piece, Bannon was also behind Sean Hannity’s retreat from criticizing Moore.
