The Senate Watergate Committee was an example of a special committee developed by the US Senate. The goal of this legislative committee was to investigate the Watergate scandal. This scandal revolved around the break-in at the Democratic National Convention headquarters at the Watergate complex in Washington D.C.

Specifically, this group was focused on exposing any corruption or cover-up activities regarding US politicians or members of the government. The biggest target of this committee became Richard Nixon, who would eventually resign from the presidency due to his connection to this break-in.

I think the answer is "Select Committee"
