If Trump is able to succeed in creating a legal buffer by curtailing the Mueller investigation and getting Kavanaugh on to the Supreme Court it will be with strong assistance from the Republican controlled Congress. Republican Senators could have urged Trump not to nominate Kavanaugh, but to choose a conservative with a different view of presidential power and immunity, as that is not yet a partisan or ideological issue. Similarly, at any time in the last 20 months, either House of Congress could have begun a real investigation into Trump’s relationship with the Kremlin or passed laws seeking to protect the Mueller investigation. Their failure to do that only solidified their role as co-conspirators with regards to Russia, but also to the corruption that has defined this administration.
