Sen. Ted Cruz (R-Texas) called on Tennessee to change a law honoring Nathan Bedford Forrest, a former Confederate general and the first grand wizard of the Ku Klux Klan.

“This is WRONG. Nathan Bedford Forrest was a Confederate general & a delegate to the 1868 Democratic Convention. He was also a slave trader & the 1st Grand Wizard of the KKK. Tennessee should not have an official day (tomorrow) honoring him. Change the law,” Cruz tweeted Friday.
