The Republican National Committee voted on Friday to install Donald Trump’s handpicked leadership team, completing his takeover of the national party as the former president closes in on a third straight presidential nomination.

Michael Whatley, a North Carolina Republican who has echoed Trump’s false claims of voter fraud, was elected as the party’s national chair in a vote Friday morning in Houston.

Lara Trump, the former president’s daughter-in-law, was voted in as co-chair.

Trump’s team is promising not to use the RNC to pay his mounting personal legal bills. But Trump and his lieutenants will have firm control of the party’s political and fundraising machinery with limited, if any, internal pushback.

“The RNC is going to be the vanguard of a movement that will work tirelessly every single day to elect our nominee, Donald J Trump, as the 47th president of the United States,” Whatley told RNC members in a speech after being elected.

Whatley will carry the top title, replacing the longtime chair Ronna McDaniel after she fell out of favor with key figures in the former president’s Make America Great Again movement. But he will be surrounded by people closer to Trump.

Lara Trump is expected to focus largely on fundraising and media appearances, which she emphasized shortly after being voted in, taking time in her inaugural speech to hold up a check for $100,000 that she said had been contributed that day to the party. When asked by a reporter later, she declined to say who wrote the check.

The functional head of the RNC will be Chris LaCivita, who will assume the committee’s chief of staff role while maintaining his job as one of the Trump campaign’s top two advisers.

McDaniel had been handpicked by Trump to lead the committee seven years ago but was forced out after Trump’s Maga movement increasingly blamed her for losses over the last few years.

While she got a standing ovation after her goodbye, the new leadership appeared to eagerly embrace the change. Lara Trump, accompanied by her husband, Eric Trump, was greeted like a celebrity, with members lining up to take photos with her.

With Trump’s blessing, LaCivita is promising to enact sweeping changes and staffing moves at every level of the RNC to ensure it runs seamlessly as an extension of the Trump campaign.

In an interview on Thursday, LaCivita sought to tamp down concerns from some RNC members that the already cash-strapped committee would help pay Trump’s legal bills. Trump faces four criminal indictments and a total of 91 counts as well as a $355m civil fraud judgment, which he is appealing. His affiliated Save America political action committee has spent $76m over the last two years on lawyers.

People speculating about the RNC paying for legal bills, LaCivita said, do so “purely on the basis of trying to hurt donors”. Trump’s legal bills are being covered largely by Save America, which is a separate political entity.

The new leadership team is expected to more fully embrace Trump’s focus on voter fraud and his debunked claims about the election he lost to Joe Biden. Multiple court cases and Trump’s own justice department failed to reveal any evidence of significant voting irregularities.

Whatley, an attorney, has largely avoided using Trump’s characterization of Biden’s victory and said in one 2021 interview that Biden “absolutely” had been legitimately elected and had won the majority of the electoral college votes. But he said in another interview in the weeks after the 2020 election that there had been “massive fraud”. He has also made focusing on “election integrity” a top priority for his state party in the years since.
