Rep. Tyler Olson, D-Cedar Rapids, who is also the Iowa Democratic Party chairman, on March 29 endorsed Rep. Bruce Braley, D-Iowa, for the Senate seat that Sen. Tom Harkin, D-Iowa, will vacate after next year.

According to a Braley for Congress press release, Olson endorsed Braley during a live online Facebook chat focused on entrepreneurship and small business for Iowans hosted by Braley’s campaign.

“I’m excited to endorse Bruce Braley for the U.S. Senate,” Olson said. “I make this endorsement not on behalf of the Iowa Democratic Party but as an individual — and as a longtime friend and supporter.”

Braley announced last month that he was interested in running for the Senate seat.

“I’m proud to have Tyler Olson’s endorsement. Not only is Tyler a friend, but he’s an experienced small businessman who brings a wealth of common sense experience to the Iowa House,” Braley said. “… Tyler’s support will help us get across the finish line.”

Iowa Attorney General Tom Miller, Treasurer Michael Fitzgerald, Rep. Dave Loebsack, and former Rep. Leonard Boswell have previously endorsed Braley.
