Donald Trump has been famously dismissive of the climate change issue, going so far as to call it “a hoax.”

Meanwhile, as congressional Democrats begin to wrangle with Trump over a potential overall national $2 trillion infrastructure improvement initiative, one long-time House Democrat thinks that he may have cracked the secret how to get Trump to accept climate change investments.

“You know, when it’s couched as investment in ’21st century energy and renewables,’ I would say he was somewhat favorable,” said Rep. Peter DeFazio of Oregon, chairman of the House Transportation Committee. “You know, we didn’t talk about climate change per se, but there are ways, you know.”

Trump and Democrats met last week on infrastructure and plan to meet again to move forward in a couple of weeks.

Ironically, Trump appears to be genuinely interested in working with Democrats on an infrastructure plan. However, he is reportedly seeing blowback on his right, from conservatives in Congress, and even in his own White House with opposition from acting Chief of Staff Mick Mulvaney.

Democratic Sen. Ed Markey of Massachusetts and Rep. Alexandria Ocasio-Cortez of New York, have proposed a sweeping plan to address the challenge of climate change, known as the Green New Deal.

Trump and congressional Republicans have been dismissive of the Green New Deal.
