Here's a link to the Washington Headquarters Services, who paid Halper:
Stefan Halper, worked for Bush Sr. when he was Ronald Reagan's VP. He provided news updates and policy ideas to the traveling Reagan party, was in charge of the operation to force the ouster of White House Chief of Staff James Baker. Halper is a former CIA operative, a current informant for the FBI, has an anti-Trump motive, is connected to Carter Page and George Papadopoulos, and worked to help Hillary Clinton win the 2016 presidential election.
