The California office of House Majority Leader Kevin McCarthy (R., Calif.) was vandalized on Monday, its window smashed by a boulder.
Two young men were caught on surveillance camera outside the Bakersfield office, and McCarthy posted photos of the suspects and some of the damage on Instagram, the Daily Caller reports.
"Does anyone know these two guys? They threw a boulder thru our office window and took office equipment," McCarthy wrote.
The incident is the latest in a stretch of destructive or violent acts directed at Republican lawmakers or organizations. Last month, a Republican office in Wyoming caught fire in an apparent arson attack. The building suffered moderate smoke and heat damage and had a window busted out.
Also in September, a Republican House candidate in California was attacked by a man who pulled a switchblade on him and yelled, "I'll kill you!"
Two weeks ago, the headquarters of the Manhattan Republican Party was vandalized. Those responsible broke the office's windows and left a threatening message, which said the "attack is merely a beginning."
Last week, two Republican candidates were assaulted in Minnesota and a spokesman for the state's Democratic Party was suspended for calling for violence against Republicans. Communications staffer William Davis was suspended for a week without pay after making a Facebook post joking that Democrats would "bring [Republicans] to the guillotine" the day after the midterm elections.
A few days prior to Davis' suspension, Minnesota state representative Sarah Anderson was punched in the arm after spotting a man destroying GOP yard signs. State representative candidate Shane Mekeland suffered a concussion after getting sucker punched while speaking with constituents at a Benton County restaurant.
In recent months, several prominent Democrats have challenged the role of civility in American politics.
Twice-failed presidential candidate Hillary Clinton said that civility towards Republicans has to wait until after the November midterm elections. While campaigning for Democrats in Georgia, former attorney general Eric Holder said, "When they go low, we kick them."
In June, Rep. Maxine Waters (D., Calif.) encouraged people to "create a crowd" around officials in President Donald Trump's administration and tell them they're "not welcome."
