It could also hamper Mueller's ability to turn an insider against Trump in the investigation of Russian meddling in the 2016 election.
Former Trump campaign manager Paul Manafort continued to lie to investigators even after making a plea deal according to prosecutors for Special Counsel Robert Mueller.
A federal judge rejected his appeal to delay his prison term while he waited for an appeals court to rule whether the Mueller appointment was constitutional.
"Heroes will come of this, and it won't be Mueller and his bad Gang of Angry Democrats", Trump wrote.
The filing Monday suggested that prosecutors do not consider Mr. Manafort a credible witness. "Because the sentencing will be open to the public and people will be able to hear what exactly Manafort did and did not do".
They did not immediately detail what Manafort lied about, saying his "crimes and lies" would be revealed at another time.
One of Manafort's closest business contacts for several years has been Konstantin Kilimnik, a Russia-based political operative who prosecutors have alleged has ties to the same Russian military intelligence service that allegedly hacked the Democrats.

The files describe the mode as "a true test of resourcefulness", and simply tells players to "be the last one standing". Two of the foremost authorities about Red Dead Redemption and Rockstar have outlined their opinions.
Manafort's attorneys disputed the special counsel's characterization and said their client "provided information to the government in an effort to live up to his cooperation obligations", the filing added.
Judge Randolph Moss reminded Papadopoulos that he had already waived his right to an appeal and that two other judges had upheld the legality of the Mueller appointment.
Manafort pleaded guilty to conspiracy and witness tampering on September 14, nearly a year after he was first charged and following his conviction by a jury in a separate but related case on eight tax and banking crimes.
Since pleading guilty, Manafort had met with prosecutors almost a dozen times, and though members of Mueller's team have been asking him about a wide range of topics, they're "not getting what they want", a source with knowledge of the discussions told ABC News.
Renato Mariotti, a former federal prosecutor in Chicago, pointed out the "highly unusual" nature of such a claim.
Of course this is all just speculation, and perhaps Manafort has other reasons for allegedly lying to investigators. He was previously convicted on bank and tax fraud charges following a late summer trial in Alexandria, Virginia.
Earlier Monday, former Trump campaign foreign policy adviser George Papadopoulos reported to a prison in Wisconsin to serve a 14-day sentence for lying to investigators.
