Republican lawmakers are preparing a push for the impeachment of deputy attorney general Rod Rosenstein, after he announced the indictment of a dozen Russian military intelligence officers for interfering in the 2016 election, reports Politico.

The backdrop: GOP members have been planning on removing Rosenstein "for weeks" behind the slow pace of their probe against FBI agents. Rep. Mark Meadows had an impeachment document ready at the moment Rosenstein spoke to reporters on Friday, the report says, but it's unclear when it will be formally introduced, or the level of support it would get from fellow Republicans.
