Meg Whitman, the CEO of Hewlett Packard and a top Republican fund-raiser, will make her first campaign stop for Democratic presidential nominee Hillary Clinton on Tuesday, and Denver is the venue.

Whitman will meet with Colorado business leaders for breakfast at the Crawford Hotel to discuss Clinton’s jobs plan, which includes investing in technology companies and helping small businesses succeed.

“As a proud Republican, casting my vote for president has usually been a simple matter,” Whitman said in a statement. “Not this year. The reality we face is that Donald Trump is unfit to be president. And that is why more and more Republicans are doing what I did and supporting Hillary Clinton.

“Secretary Clinton’s temperament, global experience and commitment to America’s bedrock national values make her the right choice in 2016 for President of the United States.”

Whitman ran unsuccessfully for governor of California in 2010 and was a finance co-chairwoman for Mitt Romney’s presidential run in 2012. Like Romney, she has been one of Trump’s chief critics within his own party, likening him to a fascist who lacks the temperament to be president.

Clinton rolled out her jobs plan during with a speech in Denver on Aug. 3.

“Her vision for an America that is stronger together and her plans to create jobs and help businesses succeed comes as Trump continues to avoid discussing his long record of bankruptcies, failed businesses, and unpaid contractors,” the Clinton campaign stated Monday.

Hewlett Packard’s former CEO, Carly Fiorina, who ran unsuccessfully against Trump for the Republican presidential nomination, has made at least three speeches in the Denver metro area since July 1, when she spoke at the Western Conservative Summit.

She campaigned on jobs with U.S. Rep. Mike Coffman last weekend and was a speaker at the Red State Gathering in Denver on Aug. 13.

Fiorina, who has not endorsed Trump, also was the keynote speaker at the Steamboat Institute’s Freedom Conference & Festival in Steamboat Springs Friday night.
