They say they are seeking money and endorsements from other Republicans disillusioned by Trump, their party's candidate for the November 8 presidential election. Some have received encouragement from Clinton and members of her campaign staff.

"I made the decision that I wouldn't be able to look at my grandkids if I voted for Trump," said Dan Webb, a former federal prosecutor who is a self-described "Republican for decades" working to win over prominent Republican business people in Chicago.

Trump, a New York developer making his first run at public office, has made traditional Republican donors uneasy with inflammatory statements about women, Mexicans, Muslims, and veterans, among others.

Big-name Wall Street donors can make a difference for Clinton. They could inject big money into a campaign. They might influence moderate Republicans to switch sides. Their support of Clinton challenges Trump's assertion that his business successes make him a better candidate for president.

With the political conventions barely over, the Republican effort to fund-raise for Clinton is at an early stage. Some of the groups have yet to receive contributions because they must still file paperwork under campaign finance rules.

Trump spokeswoman Hope Hicks declined comment for this story. Clinton spokesman Jesse Ferguson said business leaders were supporting Clinton because of her economic plan and because Trump "cannot be trusted."

Wary of Trump

Groups formed to support Clinton include Republicans for Her 2016, run by Republican lobbyist Craig Snyder; a grassroots organization called R4C16, led by John Stubbs and Ricardo Reyes, officials in President George W. Bush's administration; and the Republican Women for Hillary group co-led by Jennifer Pierotti Lim, an official at the US Chamber of Commerce.

The first two groups are acting independently of Clinton's own effort. The third is acting in concert with her campaign.

"We wanted to go out there and be the voice for Republicans who were feeling wary about Trump and weird about publicly endorsing Hillary," said Pierotti Lim, who spoke at the Democratic National Convention at the Clinton team's invitation.

Webb, a partner at the law firm Winston & Strawn, said he began his outreach after being approached by billionaire investor J.B. Pritzker and longtime Clinton associate Lanny Davis. Pritzker and Davis could not be reached for comment.

On Wednesday, billionaire hedge fund manager Seth Klarman said he would work to get Clinton elected because of comments by Trump he found "shockingly unacceptable." Though Klarman, who is the president and CEO of The Baupost Group, is a registered independent, a review of filings shows his political giving has largely benefited Republicans over the years, including some of Trump's rivals in the state-by-state nominating contests this year.

Whitman, Bloomberg back Clinton

Spearheading in part the Clinton effort to woo Republicans on Wall Street is Democratic strategist Leslie Dach, a former Walmart executive and aide to Bill Clinton, sources close to the Clinton campaign said.

People familiar with the Clinton drive say the Democratic nominee has spoken with Republican business leaders, including Hewlett Packard Enterprise CEO Meg Whitman, who endorsed Clinton on Tuesday.

Clinton deputies courted former Mayor Michael Bloomberg of New York ahead of a rousing speech he gave at last month's Democratic National Convention that urged Wall Street to support her.

Whether Bloomberg, a self-made billionaire media mogul and an erstwhile Republican, will play a role in courting other Republican business leaders has yet to be determined, a source close to the discussions said.

While some major donors are hesitant to back Trump, the candidate over the past month has pulled in millions of dollars in small-money donations to boost total contributions to more than $80 million for Trump's campaign and the Republican Party, nearly matching Clinton's $90 million haul during the same period.
