Activists and advocacy groups are ramping up the pressure on undecided senators with hopes of tanking Supreme Court nominee Brett Kavanaugh, with less than three weeks to go before Republicans hope to confirm him.

Outside groups are pouring hundreds of thousands of dollars into the effort to oppose Kavanaugh, and are targeting GOP senators such as Susan Collins of Maine, Dean Heller of Nevada, and Lisa Murkowski of Alaska, as well as Democrats in Republican-leaning states up for re-election who decide to vote “yes.” Many of those same senators are being subjected to cruder attacks from individuals.
