Sen. Cory Gardner, R-Colo., had been reluctant to back GOP nominee Donald Trump. He finally decided to do so late last week and issued another statement this week for those who'd missed the message.

On Tuesday, the Colorado politician issued a statement saying "no good Republican could ever support Hillary Clinton for president."

AP then reported that he had first told attendees at a fundraiser in Colorado Springs, Colo., on Friday that he would be voting Republican "up and down the ticket."

"A Republican president will make the difference, even a Republican president named Donald Trump," Gardner told guests.

For months, the Colorado politician, not up for re-election until 2020, had refused to back the billionaire businessman. He first came to Washington in 2014 on promises to shake up Congress and stand up to President Obama, similar in some ways to Trump's message.
