Vandals have lashed out at the leaders of the US House and Senate, spraying graffiti on their homes and in one case leaving a pig's head.
It comes as US Congress failed to approve an increase in the amount of money being sent to individuals to help cope with the coronavirus pandemic.
Senate Majority Leader Mitch McConnell's door was covered in graffiti in Kentucky on Saturday. It read: "WERES MY MONEY."
"MITCH KILLS THE POOR" was scrawled over a window. A profanity directed at the Republican senator was painted under the mailbox.
At House Speaker Nancy Pelosi's home in San Francisco, someone sprayed graffiti and left a pig's head and fake blood on New Year's Day, police said.
A special investigations unit is trying to determine who did it.
News station KGO-TV reported that graffiti found on the garage door of the Democratic leader's home included the phrases "$2K," "Cancel rent!" and "We want everything," apparently referencing Democratic lawmakers' failed efforts to increase the coronavirus relief checks from US $600 to $2000.
McConnell released a statement on Saturday condemning the vandalism at his home in Louisville.
"I've spent my career fighting for the First Amendment and defending peaceful protest," he said.
"I appreciate every Kentuckian who has engaged in the democratic process whether they agree with me or not. This is different. Vandalism and the politics of fear have no place in our society."
McConnell said he and his wife were not intimidated by the vandalism.
On New Year's Day, Senate Republicans refused to allow debate over a bill to increase the amount of COVID-19 relief.
The increase, supported by President Donald Trump, passed the Democratic-led House but was blocked by McConnell.
The government has begun sending out the smaller payments to millions of Americans. The $600 payment is going to individuals with incomes up to $75,000.
