WASHINGTON (AP) — The first two Democratic presidential debates for the 2020 election will have room for up to 20 candidates who meet certain polling or fundraising thresholds.

The June and July events will involve two waves of up to 10 candidates each. Participants will be assigned randomly.

A senior Democratic National Committee official outlined the framework Thursday for the events.

Candidates can qualify by reaching 1 percent support in at least three national or early primary state polls. They also can qualify by collecting campaign donations from at least 65,000 individuals, with at least 200 unique donors in at least 20 states.

NBC, MSNBC and Telemundo will broadcast the June debates on back-to-back nights.

CNN will broadcast the July debate on back-to-back nights.

Dates and locations will be determined later.
