President Trump plans to host a group of Republican senators at the White House on Monday night as he seeks to persuade them to back the Senate's new healthcare bill.

White House press secretary Sean Spicer announced the meeting but declined to provide a list of senators expected to attend.

Later in the evening, a White House official said the following GOP senators were attending: No. 2 Senate Republican John Cornyn John CornynCalls grow for Biden to expand election map in final sprint Bipartisan praise pours in after Ginsburg's death Chamber of Commerce endorses McSally for reelection MORE (Texas), Lamar Alexander Andrew (Lamar) Lamar AlexanderToobin: McConnell engaging in 'greatest act of hypocrisy in American political history' with Ginsburg replacement vote Chamber of Commerce endorses McSally for reelection Trump health officials grilled over reports of politics in COVID-19 response MORE (Tenn.), Roy Blunt Roy Dean BluntCDC tells Congress it urgently needs billion for vaccine distribution On The Money: Trump undercuts GOP, calls for bigger COVID-19 relief package | Communities of color hit hardest financially by COVID-19 | Businesses, states pass on Trump payroll tax deferral Trump undercuts GOP, calls for bigger COVID-19 relief package MORE (Mo.), Steve Daines (Mont.), James Lankford (Okla.), Richard Shelby (Ala.), and John Thune John Randolph ThuneWhat Senate Republicans have said about election-year Supreme Court vacancies The Hill's 12:30 Report - Presented by Facebook - Don't expect a government check anytime soon The Hill's Morning Report - Sponsored by The Air Line Pilots Association - Trump contradicts CDC director on vaccine, masks MORE (S.D.).

Senate leaders face a tough task in generating momentum for their plan to repeal and replace ObamaCare.

According to The Hill's whip list, Daines and Lankford are undecided on the bill, while the other White House guests are leaning toward supporting the current draft.

The Arizona Republican will be out of pocket this week as he recovers from surgery. He hopes to return next week, though that is not guaranteed.

Nonetheless, Spicer voiced optimism that the Senate will pass the bill repealing and replacing ObamaCare.

"We have every confidence in the majority leader's ability to get this done," Spicer said.
