From the MSNBC website:
The Trump administration could refuse to comply with Democrats who attempt to investigate issues like Trump’s ties to Russia, or corruption in the White House in 2019. Former Counsel to Speaker Nancy Pelosi during the Bush administration, Irvin Nathan, who was also the first House Counsel to take a White House to court over an administration subpoena, won his case. He joins Ari Melber exclusively to discuss how Democrats can subpoena top White House aides if they refuse to comply with subpoenas. Nathan also reveals Pelosi is already considering candidates for the Counsel role, and hopes the court battle begins “very quickly”.
