Who are the left-wing groups protesting outside the homes of GOP lawmakers?

Somber mourners have paid respect to Ginsburg outside the Supreme Court in Washington, D.C., but other protesters have also gathered outside the homes of Senate Majority Leader Mitch McConnell, R-Ky., and Senate Judiciary Committee Chairman Lindsey Graham, R-S.C.

Both lawmakers are on board with Trump's intent to nominate a new Supreme Court justice this month, prompting action from left-wing groups like Sunrise Movement and ShutDownDC.

The biggest donation to the Sunrise Movement this election cycle is $500,000 from The Sixteen Thirty Fund, according to Open Secrets. Politico reported on The Sixteen Thirty Fund in 2019, noting that it spent $141 million on more than 100 left-wing causes during the midterm election year – from pushing back against the nomination of Supreme Court Justice Brett Kavanaugh to weighing in on voting laws and minimum wage ballot measures. Politico described it as an "unprecedented gusher of secret money" that boosted Democrats and liberal causes.
