A group of Republicans infuriated at the investigation into Russian meddling in the election have launched a bid to impeach Rod Rosenstein, the man overseeing Robert Mueller’s work.

Mark Meadows, a congressman from North Carolina, said Mr Rosenstein, the deputy attorney general, had behaved in a “reprehensible” way.

He and his 10 colleagues argue that Mr Rosenstein, who supervises the Mueller inquiry, has kept congress in the dark about the progress of the investigation.

Mr Mueller was appointed by Mr Rosenstein in May 2017, after Mr Sessions recused himself. Mr Rosenstein is the only person with constitutional authority to fire Mr Mueller, and must approve matters that fall inside his jurisdiction.

Mr Mueller must also follow justice department regulations and consult with Mr Rosenstein about how to handle matters outside his jurisdiction.

Mr Rosenstein is charged in five articles of "high crimes and misdemeanors" for failing to produce information to the committees - even though the department has already provided politicians with more than 800,000 documents - and of signing off on what some Republicans say was improper surveillance of Trump adviser Carter Page, with a FISA warrant. That warrant was also signed by a federal judge.
