A senior administration official congratulated reporters on receiving tax cuts Thursday during a year-end briefing at the White House called to highlight President Trump's accomplishments.

"I hope you like your tax cut or bonus," the senior official told a room full of journalists after giving a rundown of 2017 happenings and describing future ambitions.

Officials declined to make their rosy reflections on the record, but stressed the passage of 81 pieces of legislation crowned by this week's tax cut bill, which also repeals Obamacare's individual mandate and opens an Alaska wildlife refuge to oil drilling.

"He's had an amazing first year, and many people in the country continue to see the sacrifices he's made to be here," one of the senior administration officials said.

"We've inherited a sinking battleship and tried to sink the anchor in the ocean and turn it around in a different direction," she said.

She said repeal of the individual mandate removes "the heart of Obamacare."

That official expressed befuddlement when a reporter asked if Trump had made hiring errors during his first year in office, evidenced by a large number of firing or resignations.

"No, the president didn't make a mistake. Why would you think that?" she said, adding that "we have a really good team here and a team that is very well managed by the chief of staff ... it would have to be individual by individual, and I don't play that game."

A different senior administration official predicted that Trump would sign the tax bill Friday.

"I think there's a very good chance the president signs it tomorrow," he said, though the official said Wednesday the bill signing needs to wait for a spending bill that waives mandatory spending cuts.

Officials included in the discussion of Trump's accomplishments the shutdown of drug-dealing darknet market AlphaBay, the end of the Islamic State's "physical caliphate," and his moves to support construction of the Keystone and Dakota Access oil pipelines.

The officials said Democrats were responsible for a lack of bipartisan legislation so far.

One of the senior officials said legislative efforts in early 2018 would include passing legal protections for young illegal immigrants covered by the Deferred Action for Childhood Arrivals program, along with "an infrastructure package that I think will be bipartisan."

Welfare reform also is on the table, he said. "The president is more and more excited about trying to address welfare reform," he said.

The official who discussed legislation said there would be a meeting the first week of January with House Speaker Paul Ryan, R-Wis., and Senate Majority Leader Mitch McConnell, R-Ky., to discuss plans.
