The US domestic security chief on Wednesday compared current anti-Muslim sentiment to the anti-communist "Red Scare" of the 1940s and '50s, suggesting that divisive statements by Republican presidential candidates are to blame.
Homeland Security Secretary Jeh Johnson, who is black, noted that his grandfather was forced to testify in front of the House of Representatives in 1949.
"He had to, in the height of the Red Scare, to deny he was a member of the communist party, and went on to give an impassioned statement about how American negroes are patriotic," Johnson said at a conference in Washington about countering violent extremism.
