Former Trump campaign chairman Paul Manafort arrives for a hearing at the E. Barrett Prettyman Federal Courthouse on April 19, 2018 in Washington, DC.

A federal judge on Wednesday denied a request by President Donald Trump's former campaign manager Paul Manafort to suppress evidence seized by the FBI from his home as part of special counsel Robert Mueller's ongoing probe into whether Trump's 2016 presidential campaign colluded with Russia.

Manafort's lawyers had sought to limit the scope of evidence that prosecutors can rely on for his upcoming September trial in Washington, D.C., claiming that the search warrant was overly broad and unconstitutional.

"Given the nature of the investigation, the warrant was not too broad in scope," wrote Judge Amy Berman Jackson for the U.S. District Court for the District of Columbia in her ruling.
