John Hickenlooper has scheduled an event in Denver on March 7 where he is expected to join the throng of Democrats vying for the White House in 2020.

The former Democratic governor of Colorado, who has been mulling a run for months, received a permit to hold an event billed as a “celebration” in Denver’s Civic Center Park, the Colorado Sun reports. Sources close to Hickenlooper said Thursday that Hickenlooper would be announcing a run sometime during the first week of March.
