“His history of derogatory statements about women and people of color are not consistent with the values of our party,” the statement said. “When we first learned of Mr. Brock’s offensive Facebook posts, we called on him to suspend his campaign. He declined. Now, with the revelation of these racist posts, we are renewing our call, publicly, for Mr. Brock to drop out of the race and are endorsing his opponent, Kelly Fowler.”

Fowler is a real estate agent and former Virginia Beach teacher.

Brock issued a statement through an aide saying he would not drop out.

“I refuse to back down from my commitment to my grass-roots supporters and the voters of my district,” the statement said. “I believe the voters of Chesapeake and Virginia Beach should decide who their nominee is, not power brokers or special interests in Richmond.”

The 21st District seat is held by Del. Ronald A. Villanueva, R-Virginia Beach, who is the chairman of the House Transportation Committee.

In an April interview with Southside Daily, Brock said he wanted a statewide audit to determine the level of systematic racism in Virginia’s schools.
