Senate Minority Leader Harry ReidHarry ReidDems put immigration front-and-center on convention's first day Dem ad blasts Indiana senate candidate on Social Security Super-PAC targets Portman on trade MORE (D-Nev.) slammed the Republican establishment Wednesday, suggesting they should blame themselves for the rise of GOP front-runner Donald TrumpDonald TrumpDems flirt with disaster on convention’s first day Trump: Bernie gave up, ‘did all that work for nothing’ Sanders fires back at Trump: 'Never tweet' MORE.
"Donald Trump is the Republican Party’s Frankenstein," Reid said. "Republicans have spent the past eight years stoking the fires of resentment and hatred, building Trump piece by piece."
Reid's remarks come after Trump won seven out of the 11 states that held Republican primary contests on Tuesday.
The Nevada Democrat, who is retiring at the end of his current term, suggested that after Republicans "refused" for years to work with President Obama or Democrats on legislation they are now "reaping what they have sown."
"Donald Trump is the ultimate fulfillment of the Republican Party's legacy of obstruction and resentment," he added.
While congressional Republican leadership has distanced itself from some of Trump's policies, they've also been reluctant to publicly suggest that they wouldn't support him as the party's nominee.
Reid said that Republicans "act surprised" by Trump's dominance in the polls "even as Republican leaders continue to support a man who refuses to distance himself from the Ku Klux Klan."
Reid has repeatedly used the Senate floor as well as weekly press conference to denounce Trump, who he suggests is being propped up by the Republican Party. Top Democrats are also increasingly calling on Republican lawmakers to denounce their party's presidential frontrunner.

"It's up to the Republicans to try and undo what they have done by denouncing Donald Trump," he said. "It's time for the Republicans to stop the Frankenstein they created."
