Yes, Raj Shah, he is a Bushie and he also has worked for democrats, he leaked the story about Sarah leaving the White House. I do not think he is trust worthy.
Per wiki.
As head of opposition research in the Republican National Committee (RNC) in 2016, Shah led a team of experts to carry out research against Hillary Clinton. Shah was behind the anti-Clinton campaign during the campaign. Then-incoming White House Chief of Staff and outgoing head of the RNC Reince Priebus said that Shah would be among the key leaders in helping to implement the President-elect’s agenda and bringing change.[6] Prior to the election, Shah called Trump “deplorable” and remarked that the release of the Donald Trump Access Hollywood tape was “some justice”; he also helped get embarrassing footage of Trump to use in a Jeb Bush commercial for the latter’s campaign.[7]
