As President Trump prepares to leave office in days, a lucrative market for pardons is coming to a head, with some of his allies collecting fees from wealthy felons or their associates to push the White House for clemency, according to documents and interviews with more than three dozen lobbyists and lawyers. ... A onetime top adviser to the Trump campaign was paid $50,000 to help seek a pardon for John Kiriakou, a former C.I.A. officer convicted of illegally disclosing classified information, and agreed to a $50,000 bonus if the president granted it, according to a copy of an agreement. And Kiriakou was separately told that Trump's personal lawyer Rudolph W. Giuliani could help him secure a pardon for $2 million.
