Amazon CEO Jeff Bezos and eight company executives kicked in contributions between $250 and $5,400 in an 11-day period in September to Colorado Republican Sen. Cory Gardner’s 2020 re-election campaign, according to a recent report from CNBC.

Denver has been listed among cities being considered by Amazon for a second company headquarters, although Gov. John Hickenlooper recently said he believes Denver is no longer in the running.

The contributions were made between Sept. 17 and Sept. 25.

CNBC reports that Gardner “is one of the top beneficiaries of Amazon’s campaign donations in the 2018 election cycle even though he’s not running, according to the nonpartisan Center for Responsive Politics. The two candidates above him on that list are Democratic Rep. Beto O’Rourke, who is looking to unseat Republican Sen. Ted Cruz of Texas this cycle, and Democratic Washington Sen. Maria Cantwell, who is seeking re-election in November.”

CNBC cites Gardner’s co-sponsorship of S.88, the Developing Innovation and Growing the Internet of Things Act, or DIGIT Act, as one possible reason for Amazon’s support. The act would plan for, and encourage, the growth of the Internet of Things (basically, a chip that allows devices to communicate with each other). Amazon supports the measure.

Bezos is also the single largest contributor to the With Honor Pac, a political action committee that focuses on electing veterans. He has contributed $10.1 million out of the $18.5 million it has raised to date.

According to the Federal Elections Commission, those who list Amazon as their employer have made $22.5 million in political contributions in the 2017-18 election season.
