The mother of the man accused of plowing his car into a group of counter-protesters at a white supremacist rally in Charlottesville, Va., on Saturday reportedly said she thought her son was going to an event associated with President Trump.

“I thought it had something to do with Trump. Trump’s not a white supremacist,” Samantha Bloom told The Associated Press late Saturday.

Bloom's 20 year-old son, James Alex Fields Jr., was charged with second-degree murder in connection with the incident.

Bloom also told the AP she was shocked her son had radically right-leaning views.

"I don't really talk to him about his political views," she said.

"I don't really understand what the rally was about or anything, so ... I just know there was — he did mention it was 'albright'? What is it? Al--?" she asked, apparently referring to the "alt-right" movement.

Bloom told The Toledo Blade she told her son to "be careful" before he went to the rally.

“If they’re going to rally to make sure he’s doing it peacefully," she said.

One person died in the crash and 20 others were injured, according to the University of Virginia Health System.

The Department of Justice has opened a civil rights investigation into the crash.

FBI agents have interviewed Bloom.

White supremacist groups were protesting the removal of a statue from Confederate Gen. Robert E. Lee, which sparked the violent clashes.
