It’s time again for Senate Democrats to burn the midnight oil.

Senate Democrats will launch yet another night of floor speeches on Monday night castigating the GOP’s plan to repeal and replace Obamacare, aides said — a talk-a-thon led by Sens. Patty Murray of Washington and Mazie Hirono of Hawaii that is expected to run several hours after the Senate’s 5:30 p.m. votes.

Kicking off the round of speeches Monday evening will be Hirono, who recently underwent treatment for kidney cancer and has spoken about her diagnosis as she’s made her case against Republican efforts to dismantle Obamacare. Hirono is having a second surgery on Tuesday for a lesion on her rib, a spokesman said.

“Democrats are going to keep sharing our stories and the stories of our constituents to make sure people understand how devastating and ‘mean’ Trumpcare would be for the people we represent, and to do everything we can to keep up the pressure to stop it," Murray said.

Ben Wikler, the Washington director for, on Twitter urged other liberal activists to pack the galleries in the Senate chamber Monday night to show support for Democrats and their late-night speech marathon.

Democrats also led a round of floor speeches last Monday that ended shortly after midnight.
