Senate Minority Leader Chuck Schumer could be facing headwinds in his pursuit of power, even if Democrats regain control of the upper chamber in November.
During a heated debate on Monday night, Rep. Seth Moulton, D-Mass., announced that he would not support Schumer as leader if elected, citing a need for new leadership at the top.
Moulton's primary opponent, incumbent Sen. Ed Markey, D-Mass., did not explicitly endorse Schumer for leader but has supported him in the past. Markey's campaign stated that "we need a big debate about new leadership in the Senate – the direction of the Senate."
This move marks a significant departure for both Democrats, as the primary for Massachusetts' Senate seat has been marked by bitter accusations on both sides.
Moulton has accused Markey of selling out his beliefs by taking money from fossil fuel groups, while Markey has attacked Moulton for investing in defense companies and his prior comments on transgender participation in youth sports.
Moulton has a history of challenging his party's leadership, having led a rebellion within his caucus to challenge former Speaker Nancy Pelosi in 2018.
Younger candidates like Moulton are challenging the establishment left in races across the country, arguing that the status quo is not working for Americans today.
Schumer is not up for re-election until 2028, but he must face his fellow Senate Democrats every two years in the internal leadership race to make a case for why he should stay at the helm.
Other younger candidates, including Sen. Chris Murphy, D-Conn., and Abdul El-Sayed, a Democratic socialist running in the Michigan Senate primary, have also expressed concerns about Schumer's leadership.
In fact, Elissa Slotkin, D-Mich., has called on Schumer to step aside and make way for new leadership.
Schumer's office and Markey's campaign have been reached out to for comment on Moulton's remarks.
