NEW YORK, NY – New York billionaire Michael Bloomberg launched his campaign less than three weeks ago, but he is already making his first foreign trip as a presidential candidate.

The Democrat will appear Tuesday at a United Nations global climate conference in Madrid, where he'll share the results of his private push to organize thousands of U.S. cities and businesses to abide by the terms of a global climate treaty that the Trump administration is working to abandon. The appearance comes as Bloomberg, a former Republican whose dedication to the environment earned him the designation of special UN envoy for climate action, tries to find his footing in the 2020 Democratic presidential primary election.

It's rare for a presidential candidate to step onto the international stage before securing the nomination, and virtually unheard of for a candidate to do so in the first month of his or her candidacy.

Earlier this year, Bernie Sanders appeared in Canada to highlight his fight to lower prescription drug costs, while former candidate Beto O'Rourke met with asylum seekers in Mexico. Both men represented states that bordered those countries, however, and there were no formal talks with foreign leaders involved.

Bloomberg shared his plan to appear at the global climate conference on social media on Monday.

“I’m going to the climate summit in Madrid because President Trump won’t,” he said, adding that he plans to “meet with environmental leaders from around the world about next steps on tackling the climate crisis.”

Bloomberg also vowed in a statement to rejoin the Paris climate agreement in his first official act as president.

Campaign aide Brynne Craig said climate would be “a central issue” for Bloomberg this week and throughout his presidential run.
