U.S. Sen. Elizabeth Warren on Saturday will become the first top-tier Democratic presidential candidate to open a campaign office in Kansas City, Missouri.

The Massachusetts senator is expanding her presence in Missouri ahead of the state’s March 10 primary, when 68 delegates will be up for grabs, the Kansas City Star reported.

The campaign also is recruiting Kansas City-area volunteers to travel to Iowa on Saturday to canvas for Warren.

Brooklynne Roulette Mosley will head Warren’s Missouri presence. She previously served as campaign director for the Kansas Democratic Party in 2018, when Democrats retook the governorship and a congressional seat. Mosley went on to work for Kansas Gov. Laura Kelly before leaving for a job on Warren’s campaign.
