UPDATE 9:14 a.m.:
Tom Perez responded to President Trump's claim that the Democratic National Committee race was "rigged" by turning the same criticism against Trump in a CNN interview.
"We need to look at whether this race was rigged by Trump and his buddy Vladimir Putin," Perez said. He added that letting Attorney General Jeff Sessions investigate accusations of Russian involvement would amount to the "fox guarding the henhouse."
Sen. Bernie Sanders (I-VT) also responded to those claims in a separate CNN interview, insisting the race was not rigged.
When asked if Sanders would share his mailing list of progressive supporters to the DNC, Sanders deflected, saying he would support candidates who would "stand up to the 1 percent."
Sanders warned Perez not to follow the Democratic Party's status quo.
A day after the Democratic National Committee elected Tom Perez as its new chairman, President Trump called the race "totally 'rigged.'"
The race's most prominent candidates were Perez, who was the Labor Secretary under President Obama, and Rep. Keith Ellison (R-MN), endorsed by Sen. Bernie Sanders (I-VT) and much of the party's left wing.
On Saturday, Trump congratulated Perez sarcastically, saying he "could not be happier for him, or for the Republican Party."
The race for DNC Chairman was, of course, totally "rigged." Bernie's guy, like Bernie himself, never had a chance. Clinton demanded Perez!— Donald J. Trump (@realDonaldTrump) February 26, 2017
Here's the tweet where Trump insisted the race was rigged.
Congratulations to Thomas Perez, who has just been named Chairman of the DNC. I could not be happier for him, or for the Republican Party!— Donald J. Trump (@realDonaldTrump) February 25, 2017
Here's his initial tweet.
This might sound familiar
During his presidential campaign, Trump repeatedly criticized the DNC, saying it rigged the primaries in favor of Hillary Clinton. Leaked DNC emails showed some members favoring Clinton over Sanders, which led to accusations that the race was "fixed" and to former chairwoman Rep. Debbie Wasserman Schultz's (D-FL) resignation.
This time around, Trump claimed, "Clinton demanded Perez!" Former Vice President Joe Biden endorsed Perez alongside several members of Obama's cabinet.
Leaked e-mails of DNC show plans to destroy Bernie Sanders. Mock his heritage and much more. On-line from Wikileakes, really vicious. RIGGED— Donald J. Trump (@realDonaldTrump) July 23, 2016
Trump called that race "rigged" as well.
Perez fired back at Trump's congratulatory tweet on Saturday.
Ellison tweeted congratulations of his own to Perez.
But some progressives sided with Trump on this issue.
