(CNN) A Democrat from Wisconsin running to replace House Speaker Paul Ryan in Congress was arrested and pleaded guilty to driving while intoxicated in 1998, in addition to eight other arrests, according to documents obtained by CNN.

Two of Randy Bryce's arrests were more recent -- in 2011 and 2018 -- while protesting the policies of Ryan and Wisconsin's GOP Sen. Ron Johnson, but the majority of Bryce's arrests stem from a single incident of driving under the influence, including three times for driving with a suspended license.

Bryce launched his campaign in June 2017 to replace Ryan in Wisconsin's 1st Congressional District and quickly became a rising star for many progressives because of his support for unions, Medicare for all, a $15 hourly minimum wage, paid family medical leave and abolishing the Immigration and Customs Enforcement agency. Ryan announced in April that he wouldn't run for re-election and CNN rates the race as competitive, though it leans Republican.

Bryce is facing Janesville School Board member Cathy Myers in a Democratic primary on August 14. Bryce had raised a total of around $4.8 million as of March 31, the most recent records available from the Federal Election Commission.

Bryce's time in the political spotlight has brought out some unflattering aspects of his past, including the revelation that he was two-and-a-half months delinquent on paying child support to his ex-wife in September 2015, and it took nearly two years for him to pay it off. And this week, the Milwaukee Journal Sentinel reported that Bryce blamed unions for many people thinking that unions are useless and and outdated because, he said, "The labor movement has become lazy."
