Seth Meyers played mediator in the dispute between Bernie Sanders and Hillary Clinton over the fossil fuel industry on Monday's episode of NBC's "Late Night." 

In his "Closer Look" segment, Meyers recapped the tense back-and-forth between the Sanders and Clinton campaigns that began after Sanders started criticizing Clinton on the campaign trail for allegedly accepting money from the fossil fuel industry. Sanders has suggested that Clinton might not adopt more progressive environmental policies as a result, while Clinton has been vigorous in her rebuttal of Sanders' allegations, telling an activist in a rope line at a New York rally last week that she was "sick of the Sanders campaign's lying." 

Meyers first defended Clinton, citing a Washington Post fact-checking report calling Sanders' criticism an "exaggeration" and pointing out that he has also received money from the employees of fossil fuel companies. 

“It’s important to note that the role of money in politics goes way beyond any one individual candidate,” Meyers joked. “After all, money doesn’t always buy votes or win elections. Jeb Bush spent $130 million and couldn’t even buy a round of applause.”

However, Meyers then accused Clinton of being a bit hypocritical in her disdain of Sanders' tactics. The comedian pointed out that Clinton had used the same attack against President Barack Obama when the two were running against each other in the 2008 Democratic primary race. 

"I approve this message," Meyers chided, after playing a 2008 Clinton attack ad criticizing Obama for accepting donations from the employees of large fossil fuel companies, "unless someone uses a similar attack against me in eight years, in which case: How dare you!"

Sanders and Clinton will have the chance to flesh out the fight in person. The two candidates agreed to a debate in New York on April 14, five days before the key April 19 primary in the state. The debate will be held in Brooklyn and will be carried by cable news channels CNN and NY1.
