Major Republican donors rallied behind Donald Trump, pledging millions of dollars to support the first convicted felon running for U.S. president on a tumultuous day for his election campaign.

A New York jury found Trump guilty on Thursday of falsifying documents to cover up a payment to silence a porn star ahead of the 2016 election.

Many conservative donors already viewed the New York hush money cash as political persecution, echoing the Republican presidential candidate’s claim that Democrats are trying to weaken him ahead of the Nov. 5 election against Democratic President Joe Biden. Prosecutors have dismissed those claims as untrue.

In a flurry of support on Thursday, mega donors including casino billionaire Miriam Adelson and hotelier Robert Bigelow lined up behind Trump, with their donations set to bolster a wave of pro-Trump ads, door-knocking and phone banking in battleground states.

The verdict also spurred some longtime Trump donors to boost their financial support for Trump – and, in at least one case, make a big donation to him for the first time.

Robert Bigelow, who is one of Trump’s top supporters having already given over $9 million to an outside group supporting him, said criminal proceedings against Trump were a “disgrace.”

Don Tapia, a former Trump ambassador to Jamaica, said he and a small network of family and friends with whom he donates had planned to give around $250,000 this election to support Trump.

After Thursday’s conviction, Tapia told Reuters the group would aim to give over $1 million to the pro-Trump spending group MAGA Inc in coming weeks.

A Silicon Valley tech investor, Shaun Maguire, posted on social media site X after the verdict that he had donated $300,000 to support Trump.

The interviews with Reuters and a cross section of other views show the depth of Trump’s donor support despite his legal woes, suggesting he will retain significant financial firepower against Biden including from Wall Street, tech and the oil sector.

The donors interviewed by Reuters were also broadly upbeat about Trump winning in November based on a number of public opinion polls that put Trump ahead against Biden in some battleground states.

After setting out with a fundraising disadvantage against Biden, Trump for the first time in April outraised his Democratic rival, aided by fundraising events across the country.

Andy Sabin, a metals businessman and Republican donor who supported three different candidates in the Republican presidential primary before settling on voting for Trump but has not donated to him so far, does not see the verdict having an impact.

Trump can absolutely win the election, Sabin added, “as long as he keeps his mouth shut.”

In the last few weeks, Trump has hit the fundraising trail hard, hosting high-end events from Texas to New York. He is due to host three fundraisers in California next month, according to invitations seen by Reuters, including one in left-wing San Francisco hosted by tech venture capitalists.

Wall Street has also warmed to Trump, with billionaire hedge fund manager Bill Ackman considering endorsing Trump, a source familiar with the matter said on Thursday.

Some Republican donors do remain holdouts, put off by the Jan. 6, 2021, capitol riot, Trump’s brash attitude or the prospect of Trump being sentenced to jail. “I’m on the sidelines,” said one donor unsure about whether to donate, mostly because of the “drama” around Trump.
