President Donald Trump continued his Twitter attack on special counsel Robert Mueller's Russia investigation team and "Angry Democrat Thugs" Monday morning, calling them a "National Disgrace!"

"Disgraced and discredited Bob Mueller and his whole group of Angry Democrat Thugs spent over 30 hours with the White House Councel, only with my approval, for purposes of transparency," Trump's first tweet said, misspelling "counsel."

"Anybody needing that much time when they know there is no Russian Collusion is just someone looking for trouble," he added, continuing in a second Twitter post.

"They are enjoying ruining people’s lives and REFUSE to look at the real corruption on the Democrat side - the lies, the firings, the deleted Emails and soooo much more! Mueller’s Angry Dems are looking to impact the election. They are a National Disgrace!"

He continued soon after in a third tweet:

"Where’s the Collusion? They made up a phony crime called Collusion, and when there was no Collusion they say there was Obstruction (of a phony crime that never existed). If you FIGHT BACK or say anything bad about the Rigged Witch Hunt, they scream Obstruction!"

Trump's attack is linked to a weekend New York Times report that White House Counsel Don McGahn "cooperated extensively" with Mueller's team.

Trump's Monday tweets follow up on a series of similar tweets he fired off on Saturday and Sunday.
