(Washington, DC)  --  A group of Democratic U.S. senators is requesting an investigation into U.S. Attorney General Jeff Sessions.  Oregon Senator Ron Wyden and Washington Senators Patty Murray and Maria Cantwell say they aim to find out whether Sessions violated his promise to recuse himself from the investigation into Russia's alleged interference with the 2016 presidential election.  The eleven senators are asking Inspector General Michael Horowitz to investigate after Sessions recommended that President Donald Trump fire FBI Director James Comey on May 9th.  The senators' letter to Horowitz says it appears Sessions' role in the firing of Comey directly violated his recusal.
