Kelly, who interviewed Russian President Vladimir Putin on the June 4 premiere of "Sunday Night with Megyn Kelly," said on Twitter that President Donald Trump has praised Jones and been on his show.

Since many people don't know Jones and his views, Kelly noted the importance of explaining them. NBC hasn't immediately commented on the criticism.

Nelba Marquez-Greene, whose six-year-old daughter Ana Grace was killed at Sandy Hook, said she feared that giving Jones exposure would encourage Jones' followers who have harassed her and others.

"You can't just put him in a box and say he's just a character," Ms Marquez-Greene said. "He's really hurting people."
