Sen. Bernie Sanders thinks you can expect the Republican candidates squaring off at the first official debate of the 2016 presidential campaign to have the same focus—the needs of the wealthy.

The Independent senator from Vermont and presidential hopeful made the comment in an interview on SiriusXM Progress radio.

While there has been some controversy surrounding the process determining the ten candidates that will get the main debate stage Thursday evening, Sanders said “what’s more important to me […] is what these guys are saying.”

“If you listen closely, there are obviously nuances of differences,” Sanders told host Ari Rabin-Havt. But the agenda they’ll lay out will be similar, he said.

First, he said, “they want to give more tax breaks to millionaires and billionaires at a time when the rich are getting much richer.”

“There may be one or two on there who actually have listened to the scientific community and think that climate change is real,” he added, but “most of them refuse to accept that, and none of them are prepared to act aggressively to transform our energy system.”
