Of note, Mayor William Peduto of Pittsburgh is among the group of committed mayors. Some might say his inclusion comes as an ironic twist, considering Trump's comments during the announcement that he was "elected to represent the citizens of Pittsburgh, not Paris."

In response, Peduto took to Twitter and seemed none too pleased that Trump signaled out his city and noted in a tweet that "Hillary Clinton received 80 percent of the vote in Pittsburgh." He again vowed that his city would adhere to the Paris agreement.

"This city does not support the initiatives that he is doing. This city is adamantly opposed to them," Peduto told reporters following Trump's announcement. "For him to use this city as his example of who he is elected to represent — he’s not representing us at all, or not very well."
