Until the day after mid-term elections?
The IG is an Obama appointee, by the way.
Rosenstein is also an Obama appointee - 8 years as Obama’s U.S. Attorney in Maryland - handled at least one politically sensitive investigation for Obama.
Robert Mueller is also an Obama appointee - Bush Two nominated Mueller for FBI Director, and ZERO Democrats voted against him - Obama retained Mueller for two years after the 2008 election - then, Obama gave Mueller a two year extension, and ZERO Democrats voted against the extension.
Why Trump ever agreed to keep people like this in his Administration is incomprehensible.
Unless he wanted to lease some time rent free.
