Sen. Rand Paul’s (R-KY) wife, Kelley, explains, in an interview with Breitbart's Amanda House, why she wrote an open letter to Sen. Cory Booker (D-NJ) expressing her anguish over the harm done to her husband and the “horrifying” threats the family has faced. She said Booker encouraged these threats when he told President Trump’s detractors to use acts of intimidation against the president’s supporters.
