Campaign Finance Charges - Did the Attorney General of the United States Dimiss the Campaign Finance Pleas?

Jeff burman says he was told by trump appointees to bring a prosecution against president obama's white house council despite the fact that that man had committed no crime. Trump's attorney general also told burman's office to stop investigating anybody else who was involved in the campaign finance felonies that put the president's lawyer in prison. They also tried to undo michael cohen's guilty plea, but they did delay by months any further investigation into other people involved in coen's crimes.
