Democratic Sen. Kamala Harris added fuel to speculation she is eyeing a 2020 presidential run, planning a campaign trip to Iowa ahead of the midterm elections.

The Associated Press reported Saturday that the California senator will make her first trip on Oct. 22-23 to the state with the nation's earliest presidential caucus.

Harris, a member of the Senate Judiciary Committee, has been in the news recently for her opposition to Supreme Court Justice Brett Kavanaugh. She has also planned a stop in early primary state South Carolina as well as Wisconsin in October, according to Politico.

The former California attorney general, who was elected to the Senate in 2016, has said she will seriously consider a 2020 presidential campaign after the November midterms.

Harris isn't the only possible presidential hopeful on the Democratic side. Earlier this week, former Republican New York City Mayor Michael Bloomberg kicked off speculation about a 2020 run with a Wednesday announcement he changed his political affiliation to the Democratic Party.
