In April 2018 after the FBI raided the hotel room and offices of Trump's personal attorney, Michael Cohen, Booker, along with Chris Coons, Lindsey Graham, and Thom Tillis, introduced new legislation to "limit President Trump's ability to fire special counsel Robert Mueller." Termed the Special Counsel Independence and Integrity Act, the legislation would allow any special counsel, in this case Mueller, to receive an "expedited judicial review" in the 10 days following being dismissed to determine if said dismissal was suitable.
