In energized remarks before supporters, House Democratic Leader Hakeem Jeffries said his party will deliver “transformational change” when they take control of Congress after voters fueled a blue wave that will upend President Trump’s second term and the GOP agenda.

Jeffries, who is now poised to become the first Black House speaker in history, argued voters sent Republican-led Washington a clear message that they are done with political extremism and corruption. He opened his remarks to supporters in Washington, D.C., to say “America is back,” and plans for Democrats to deliver as soon as they take control in January, with a focus on affordability.

The New York Democrat said he plans to include efforts to improve access to affordable housing, education, healthcare and retirement benefits.

“We’re going to fight to make sure that we make this country affordable for every single American,” Jeffries said. “This is a change election. And we understand as House Democrats we need to deliver dramatic change. Things are broken. We need a Congress that puts the American people first.”

Tuesday’s midterm election results will bring an end to a Republican-controlled Washington, fueled by voter anger over President Trump’s handling of the economy, the Iran war and a higher cost of living. The newly divided capital means Trump will no longer be able to rely on a GOP-led Congress that let him set the agenda. Instead, the Democratic victories will accelerate Trump’s lame duck status.

However, Democrats will face an uphill battle installing many of their more ambitious plans. For example, they’ll likely clash with Trump, who retains his power to veto legislation, when it comes to legislative efforts to address affordability concerns.

In remarks acknowledging Tuesday’s election results, House Speaker Mike Johnson told supporters in Shreveport, La., that the “grand experiment” of democracy isn’t controlled by a king or a monarch. Johnson said he “left it all on the field” to try to retain control of the lower chamber but they faced unfavorable odds.
