WASHINGTON — As an train in uncooked presidential energy, it was a flop. As a political tactic, it backfired. And as a coda to his closing weeks in workplace, President Trump’s risk to veto a $900 billion Covid reduction and authorities funding invoice merely underscored his tumultuous tenure within the Oval Workplace.

For 5 days, beginning earlier than Christmas, Mr. Trump just about held the nation hostage, delaying the extension of unemployment advantages for tens of millions of out-of-work People, holding up the supply of $600 checks, and dangling the potential of a complete authorities shutdown at the same time as officers raced to distribute a coronavirus vaccine.

After which he caved.

After calling the invoice “a shame” and mocking the checks as “measly,” the president signed the legislation into law on Sunday night, claiming to have gained concessions from Congress within the course of, together with votes to extend the person funds to $2,000. However in reality, Mr. Trump achieved little various face-saving pledges that may do nothing to considerably alter the bipartisan laws.

“It’s one other instance of the story of the Trump presidency,” mentioned Michael Metal, who was press secretary for John Boehner, Republican of Ohio, when Mr. Boehner was speaker of the Home. “He achieved just a few extra days of chaos on the finish of a chaotic presidency.”

The veto risk was the newest attention-getting maneuver by a president who seems unwilling to just accept the fact that Washington is transferring on with out him. With solely 23 days left in his time period, Mr. Trump tried — and failed — to wrest again no less than the looks that he’s nonetheless in charge of the nation’s future.

On Monday, Democrats put the president’s calls for to the check in a Home vote on rising the person stimulus funds to $2,000, an effort supposed to both win approval for heftier funds lengthy supported by Democrats or drive Republicans to reject them and defy Mr. Trump. The vote simply reached the two-thirds majority wanted to go the Home, with 44 Republican lawmakers backing the trouble.

It’s unclear whether or not the Senate will entertain such a measure. Senate Republicans have resisted rising the funds, citing considerations in regards to the federal funds deficit, and Senator Mitch McConnell, Republican of Kentucky and the bulk chief, made no point out in an announcement on Sunday of the $2,000 funds or any of the president’s assertions in regards to the subsequent steps for the chamber he controls.

Mr. Trump’s risk to scuttle a Covid reduction invoice that took months for lawmakers to agree on got here in sometimes dramatic trend: On Dec. 22, the president posted a four-minute video to Twitter wherein he breathlessly ridiculed international help spending and different examples of what he known as “pork” in a invoice that his personal Treasury secretary and Republican lawmakers had negotiated with Democrats in Congress.

“It truly is a shame,” he mentioned, citing spending that he had endorsed in his personal funds and falsely asserting that the laws “has virtually nothing to do with Covid.”

He adopted up with days of tweets, demanding that lawmakers “increase payments to the people” and cease the billions of {dollars} in “pork.” It was a repeat of the cliffhanger that he compelled the nation to endure within the spring of 2018, when Republican lawmakers succeeded in speaking the president down from his risk to veto a $1.3 trillion spending deal.

That handholding occurred once more over the vacation weekend, as two of his closest allies on Capitol Hill, Senator Lindsey Graham of South Carolina and Consultant Kevin McCarthy of California, the Republican chief, sought to steer the president to again down and signal the laws.

Mr. Graham lobbied Mr. Trump in particular person throughout a spherical of golf on Christmas Day on the president’s membership in West Palm Seaside, Fla. And Mr. McCarthy talked for hours on the cellphone with Mr. Trump, spending a lot of Sunday making an attempt to assuage the president’s considerations at the same time as he recovered from elbow surgical procedure, in line with officers accustomed to the conversations.

However whereas Mr. Trump’s choice to signal the invoice prevented the calamity of a authorities shutdown in the course of a pandemic that’s killing more than 1,000 Americans a day, even Republicans struggled to know how his veto risk achieved a lot that was constructive for the president or his celebration.

On a sensible degree, he bought little or no.

In an announcement launched after he signed the laws, Mr. Trump asserted that he was “demanding many rescissions,” a technical time period for requests by a president for Congress to permit the administration to chop spending that it determines is not essential.

However as Mr. Trump came upon when he tried an analogous tactic in 2018, it really works provided that a president can muster bipartisan assist. (That 12 months, a number of Republicans within the Senate voted towards a $15 billion rescission request by Mr. Trump.)

On Sunday, Consultant Nita M. Lowey, Democrat of New York and the chairwoman of the Home Appropriations Committee, made it clear that the president’s effort wouldn’t succeed.

“The Home Appropriations Committee has jurisdiction over rescissions, and our Democratic majority will reject any rescissions submitted by President Trump,” she mentioned in an announcement.

Mr. Trump mentioned the Home and Senate “have agreed to focus strongly on the very substantial voter fraud which befell” within the 2020 election. Actually, the Democratic-run Home is definite to disregard that cost. And even within the Senate, there may be little urge for food to hitch the president’s voter fraud campaign.

Republican management urged senators this month on a non-public name to just accept the outcomes of the election and to not be part of an effort spearheaded by some Home Republicans to overturn them.

And Congress is unlikely to embrace Mr. Trump’s name to remove protections for social media firms. He has argued with out proof that Part 230 permits web sites to censor conservative views, however knowledge exhibits that conservative personalities and publishers typically thrive on-line.

Whereas the considerations about Part 230 are bipartisan, it’s unlikely that lawmakers may attain an settlement on the problem throughout the subsequent week. Mr. Trump and his allies have but to seek out substantial frequent floor with Democrats who primarily need adjustments addressing discriminatory promoting or terrorist content material on-line.

Politically, the president’s veto threats served solely to place his Republican allies within the Home and Senate on the recent seat.

Within the Home, Republicans who have been wanting to reject $2,000 stimulus checks couldn’t merely ridicule it as an thought cooked up by Speaker Nancy Pelosi, a Democrat, who shortly seized on the president’s phrases to attempt to go a invoice that may improve the direct funds. Those that needed to vote towards the bigger quantity needed to buck their very own president — and the voters who assist him.

Consultant Kevin Brady of Texas, the highest Republican on the Methods and Means Committee, complained on the Home ground that the proposal had been “rapidly dropped on us on the final minute” and wouldn’t help those that wanted it most.

“I fear that this whopping $463 billion gained’t do what’s wanted, stimulate the financial system or assist staff get again to work,” Mr. Brady mentioned.

Within the Senate, the president’s 5 days of grousing served solely to confuse the Republican place on direct funds, which had been fastidiously calibrated with senior members of Mr. Trump’s administration.

For months throughout negotiations, Senate Republicans resisted rising the funds above $600, citing considerations in regards to the federal funds deficit. It’s unclear whether or not the Senate will even take up a vote on rising the scale of the checks.

Mr. Trump had claimed that “the Senate will begin the method for a vote” on $2,000 checks. Within the legislative lingo that guidelines the Senate, that may be a far cry from guaranteeing approval of the upper quantity.

Brendan Buck, a Republican strategist who served as a senior adviser to Paul Ryan of Wisconsin when he was Home speaker, mentioned he was deeply skeptical that Republicans would wish to take up the president’s trigger for greater stimulus funds. And Mr. Buck famous that there was virtually no time for that to occur, anyway.

“It’s not primarily based in any actuality: the substance and the politics and the clock. There’s no probability for that,” he mentioned. “It does really feel like he completely caved with out getting something, and it’s unclear to me why.”

In 4 years within the White Home, Mr. Trump has had some success in bending Congress to his will. He labored with Republican lawmakers to push via a $1.5 trillion tax reduce in 2017. His Republican allies within the Senate have confirmed a report variety of federal judges, together with three new justices on the Supreme Court docket.

However the risk to veto the Covid reduction invoice was an in the end fruitless train that may do little to bolster Mr. Trump’s legacy.
