Former Florida Rep. Carlos Curbelo, who once served on the House Ways and Means Committee and was an advocate for a carbon tax, was invited to testify at that committee’s first climate change hearing later this week. Then he was uninvited for “reasons beyond the chairman’s control” by House Majority Leader Steny Hoyer.

“It’s a shame because I thought for a couple days that Democrats might actually be interested in making bipartisan progress on climate policy,” Curbelo said. Members on both sides of the aisle expressed disappointment. From his former delegation mate:

“Republicans were looking forward to a bipartisan, solutions-based hearing for this growing national problem. With Chairman Neal rescinding his invitation of former Republican member, Carlos Curbelo, it’s clear progressive Democrats decided to make this a partisan political exercise instead,” a spokesman for the committee ranking member Rep. Kevin Brady said.

Since leaving Congress, Curbelo has been working with multiple pro-carbon tax groups . According to a Twitter post, he plans to publicly release his testimony.
