U.S. Sen. Elizabeth Warren and congressional candidate Ayanna Pressley are headlining a "Unity Rally'' for the Massachusetts Democratic Party.
The Sunday event happens at the Cambridge Community Center in Warren's hometown of Cambridge.
Warren and Pressley are expected to speak about the importance of supporting Democratic candidates in the November election.
Warren faces Republican state Rep. Geoff Diehl, who served as co-chairman of President Donald Trump's 2016 campaign in Massachusetts.
Pressley is a Boston City Councilor who defeated longtime U.S. Rep. Michael Capuano in a stunning primary upset that's garnered national attention.
She's running unopposed in November and is poised to become the first black woman the state will send to Congress.
Democrat Jay Gonzalez, who will face Republican Gov. Charlie Baker in November, also plans to attend the rally.
