Across New York City, Black Lives Matter murals have been painted on the streets.
Washington, D.C. was the first US city to get a giant yellow "Black Lives Matter" mural when Mayor Muriel Bowser had it painted on the street leading to the White House.
Nichole Anderson, 42, and David Nelson, 53, both of Martinez, also face counts of vandalism and possession of tools to commit vandalism, the Contra Costa County district attorney's office said.
Zaria Gilmore, another painter, said that she is not surprised "to see there are people who thought they were entitled enough to paint over what we've done here".
BLM is an organized movement advocating for non-violent civil disobedience in protest against incidents of police brutality against African-American people.
"We must address the root and byproduct of systemic racism in our country", Becton said.
President Trump derided the mural plan last week, saying it would be "denigrating this luxury Avenue" and antagonize the city's police as "a symbol of hate". "It's a leftist lie".
Residents are keeping an eye out for potential vandals, according to The New York Times.
A message seeking comment left on a phone number listed for Anderson and Nelson was not immediately answered.
The incident occurred directly after the mural was completed, right in front of the courthouse located in Martinez, California, a city outside of San Francisco. "We must continue to elevate discussions and actually listen to one another in an effort to heal our community and country". They face a maximum of up to a year in jail if convicted.
