"Senator Markey is a good man, but it's time for a new generation of leadership," Moulton asserted in the video.
Markey was first elected to Congress in 1976 and served as a U.S. representative until 2013, when he became a senator. He has held his Senate seat for 12 years.
Moulton's challenge could set the stage for a generational shift within the Democratic Party, which struggled last election cycle after Biden was forced to drop out of the race in July, leaving then-Vice President Kamala Harris with just 107 days to run her presidential campaign. She lost every swing state and the popular vote to now-President Donald Trump.

Markey will be put to the test once again in November 2026. If he defeats Moulton, Markey will be 86 at the end of his next term.
Fox News Digital reached out to Markey and Moulton's offices for comment.
