Senate Majority Leader Mitch McConnell lashed out at House Minority Leader Nancy Pelosi in his opening floor speech Monday, criticizing his Democratic counterpart across the Capitol for using “irresponsible racial invective” in her attack on President Trump’s immigration proposal.

Pelosi last week called President Trump’s plan to provide a pathway to citizenship for 1.8 million so-called Dreamers a "campaign to make America white again,” because it would fund border security and end chain migration and the diversity visa lottery system.

“Constructive critiques are one thing,” McConnell said. “But the type of irresponsible racial invective used yet again on this subject by the Democratic leader in the House is decidedly unhelpful.”

McConnell said Pelosi’s words would make it harder for the two parties to strike a bipartisan deal on immigration reform legislation.

“I urge my Democratic colleagues to put serious, good discussion ahead of cheap, partisan point scoring,” McConnell said.

He praised Trump’s outline, which he said provided an indication of what the president would sign into law.

McConnell told lawmakers to “look to this framework” as they negotiate on a Senate bill.

Pelosi spokesperson Drew Hammill accused McConnell of ignoring Trump's recent comments made in a White House meeting in which he referred to some underdeveloped nations as "sh—holes."

"Mitch McConnell has found his voice," Hammill said in a statement to the Washington Examiner. "When President Trump used racial ‘invective’ to insult African and Caribbean nations, he couldn’t find the courage to say a thing. Apparently, Senator McConnell is more offended by pointing out the administration's dog whistles than the hateful bigotry itself."
