A federal judge in Florida has sanctioned former President Donald Trump and his attorney Alina Habba, ordering them to pay fines of nearly $1 million for filing what he deemed to be a frivolous lawsuit claiming that Hillary Clinton and others involved in the Russia investigation unlawfully conspired to damage Trump’s reputation.

The opinion from Judge David Middlebrooks calls Trump “a prolific and sophisticated litigant who is repeatedly using the courts to seek revenge on political adversaries.”

“He is the mastermind of strategic abuse of the judicial process, and he cannot be seen as a litigant blindly following the advice of a lawyer. He knew full well the impact of his actions,” Middlebrooks wrote in his opinion.

“As such, I find that sanctions should be imposed upon Mr. Trump and his lead counsel, Ms. Habba,” wrote the judge.
