House Minority Leader Hakeem Jeffries said Thursday that a Democratic victory in the midterm elections would lead to aggressive oversight of President Donald Trump, including efforts to address what he described as corruption across Washington.

Speaking on MS NOW’s “All In,” Jeffries argued that Trump has acted as though he should not be subject to the same standards as other presidents. “Donald Trump likes to conduct himself as if he should be held to a standard different than every other American president or former president. And we can’t allow that to happen on all of the things,” Jeffries said.

Jeffries said a Democratic-controlled House would focus both on policy priorities and oversight. “And certainly it’s going to be the case that in a Democratic majority, we’re going to fight hard to tackle the issues that matter, to drive down the high cost of living, fight hard, fight hard, to fix our broken health care system, of course,” he said. He added that Democrats would also move to address ethics concerns throughout the federal government. “But also at the same time, we’ve got to clean up the corruption that exists in Washington, DC, in the Congress, with the Supreme Court, and also deal with Donald Trump and his administration, who spend all of their time. It seems like trying to enrich themselves, their family and their friends, as opposed to focusing on doing their job to make life better for the American people.”

Jeffries said Democrats intend to use the House’s constitutional role as a check on executive power. “We will hold the Trump administration accountable in a manner consistent with what the House should be all about a check and balance on an out-of-control administration,” he said.

Looking ahead to November, Jeffries predicted electoral losses for Republicans, saying Trump is aware of the political stakes. “Donald Trump understands that if there is a free and fair election in November, and we’re going to make sure there is one, that the House is lost, Democrats are going to take back control of the House of Representatives,” Jeffries said.

He also suggested the GOP’s prospects in the Senate are weakening. “And the Senate is looking increasingly shaky as well, because the American people are rejecting this extremism. Donald Trump and Republicans have failed,” Jeffries said.
