President Trump is escalating his criticism of Senate Judiciary Committee Chair Chuck Grassley (R-Iowa) for his unwillingness to overhaul the “blue slip,” a move that has further dismayed Senate Republicans.

The Judiciary Committee chair, and his fellow Republicans, have so far brushed off pressure from the president to nix the long-standing practice.

President Donald Trump renewed his demand for the Senate's "blue slip" tradition to be done away with and urged Senate Judiciary Chair Chuck Grassley to tell Democrats to "go to HELL."
