Senate Judiciary Committee Chairman Lindsey Graham (R-SC) sent letters Friday to State Department and Justice Department officials regarding communication between one State Department official and Christopher Steele.

Graham’s letters to Pompeo and Horowitz arise as Attorney General William Barr said the DOJ will continue to investigate how the FBI obtained FISA warrants to surveil the Trump campaign during the 2016 presidential election. Barr said during a recent hearing that he believes Horowitz’s investigation into the FISA warrant issue could wrap up as soon as May or June.
