Kellyanne Conway, the campaign manager for Donald Trump's campaign, lamented Tuesday that it is "incredibly disappointing" that Hewlett-Packard CEO and top Republican fundraiser Meg Whitman is actively supporting former Secretary of State Hillary Clinton.

Appearing on Fox News Radio's "Kilmeade & Friends," Conway told host Brian Kilmeade that it is disappointing that she isn't supporting Trump after Whitman stumped for Clinton in Denver on Monday. Whitman, who was the 2010 GOP gubernatorial nominee in deep blue California, is one of the few Republicans not only to not support Trump, but actively campaign for Clinton.

"It's incredibly disappointing, but it's more disappointing than surprising," Conway said.

"Let's remember: Meg Whitman lost her own race by 12 points," Conway said, referring to her 14-point defeat by Gov. Jerry Brown in 2010.

"She lost women handily by double digits. She lost Hispanics. She lost African-Americans — by the way, Donald Trump was not at the top of her ticket. It tells you something that people who run as Republicans but don't run as conservative Republicans and try to show a contrast and her opponent at the time, Barbara Boxer as I recall, they lose."

Conway went on to group Whitman and former Massachusetts Gov. Mitt Romney in the same category, referring to Romney's retreat earlier this year in Park City, Utah, where Trump's candidacy took center stage.

Conway suggested that they should have discussed the "gaps" in the FBI's hunt for "lone-wolf" terrorists, adding that the shooting at a gay nightclub in Orlando, Fla., occured during the same weekend.

"They had this opportunity to talk about how we can defeat radical Islamic terrorism and they're talking about Donald Trump. I think the 'Never Trump' movement ends up being never happy because Donald Trump is giving economic speeches that he's consulting with Reagan's economic advisers," Conway said, rattling off a few other issues Trump has emphasized in recent weeks.

"He's running the way these folks should want a Republican nominee to run, but they're never happy," Conway said, adding later on that they are still welcome to come on board and support Trump.
