President Donald Trump is "very confident" that the Republican tax plan will be passed by Congress and "we would love to see some of the Democrats come on board," White House press secretary Sarah Huckabee Sanders said Friday.
"We certainly are very confident that we'll get this package passed," Sanders told reporters at the daily briefing.
"We would love to see some of the Democrats come on board and support this historic piece of legislation that we feel will it be one of the great legacies of this presidency."
The Republican-controlled House passed its version of the tax proposal on Thursday, on a 227-205 vote along party lines, with no Democratic support.
The Senate is expected to take up its package on floor after Thanksgiving.
In addition, Arizona GOP Sen. John McCain said Friday that he supported the plan, while Alaska Sen. Lisa Murkowski opposed the addition that would repeal the Obamacare mandate.
With Republicans holding a 52-48 majority in the Senate, Majority Leader Mitch McConnell of Kentucky cannot lose more than two GOP votes to pass the reform plan.
Maine Sen. Susan Collins also has expressed concerns about rolling back the Obamacare mandate in the tax plan.
In addition, Wisconsin Sen. Ron Johnson said Wednesday that he would not support the bill in its current form.
Sanders told reporters Friday that "we'll hold out hope that Democrats in the Senate will put bipartisan politics aside and put the people of this country first.
"We haven't ruled it out.
"We're pushing forward — and we're confident we'll get it done," she said, adding: "The American people won't be pleased because they'll lose out the most if this doesn't go forward."
