WASHINGTON — The White House now has no intention of releasing President Donald Trump’s tax returns, said a top presidential adviser, stepping away from a campaign promise that he would do so when an audit of them is completed.

“The White House response is that he’s not going to release his tax returns. We litigated this all through the election. People didn’t care. They voted for him,’’ said Kellyanne Conway, counselor to the president, on Sunday.

Conway made her comments upon being asked in an appearance on ABC’s “This Week’’ about a White House petition posted on Friday demanding Trump’s returns be released. There are well over the 100,000 signatures required to meet the threshold to get a White House answer.

Conway dismissed the observation about the signatures. She said people don’t care about tax returns from Trump, the nation’s first billionaire president, and are instead focused on what their own tax returns will look like while the Republican is in the White House.

“People want to know they will get tax relief,’’ she said. Conway added that Trump and his family are complying with all ethical rules.

The Justice Department said in a memorandum dated Friday that one family member, Trump’s son-in-law Jared Kushner, isn’t prohibited by a federal antinepotism statute from taking a post as senior White House adviser.

During the campaign, Trump refused to make his filings public, saying they were under audit by the Internal Revenue Service and saying he would release them after that review is complete.

Tax experts and IRS Commissioner John Koskinen have said such audits don’t bar taxpayers from releasing returns.

After Conway’s remarks Sunday, the website WikiLeaks called on leakers to provide it with copies of Trump’s tax returns.

“Trump’s breach of promise over the release of his tax returns is even more gratuitous than Clinton concealing her Goldman Sachs transcripts,’’ WikiLeaks said in a Twitter post, a reference to Trump’s Democratic presidential rival, Hillary Clinton.

WikiLeaks during the 2016 campaign published thousands of e-mails and internal documents hacked from the Democratic National Committee and top advisers to Clinton.

The petition about Trump’s returns was posted to the White House “We the People’’ website. It was created on Jan. 20 — Inauguration Day — and demanded to “immediately release Donald Trump’s full tax returns, with all information needed to verify Emoluments Clause compliance.’’ 

It goes on to read: “The unprecedented economic conflicts of this administration need to be visible to the American people, including any pertinent documentation which can reveal the foreign influences and financial interests which may put Donald Trump in conflict with the emoluments clause of the Constitution.’’

In a separate development Sunday, White House chief of staff Reince Priebus said Trump’s first full week in office will include action on trade, immigration, and national security.

Priebus suggested Trump will sign some executive orders to alter some of former president Barack Obama’s policies but did not outline specifics.

During an appearance on ‘‘Fox News Sunday,’’ Priebus also said that Trump was feeling the weight of the presidency when he stepped into the Oval Office for the first time. But Priebus said that Trump was ‘‘still the same person’’ and was ‘‘remarkably consistent.’’

‘‘I can promise you he wants to make people proud,’’ Priebus said.

Also Sunday, Trump swore in his senior White House team in a ceremony in the East Room. He said their work isn’t about party or ideology, ‘‘it’s about serving the American people.’’

Trump praised his team’s talent, but he also joked that if his advisers are not doing their jobs well, ‘‘I will let you know.’’

Trump attended a White House reception for law enforcement officers and first responders who helped with his inauguration. He singled out the work of FBI Director James Comey, whom he offered a handshake and hug.

The Trumps celebrated their 12th wedding anniversary Sunday.
