Former House Speaker Newt Gingrich and former New York City Mayor Rudy Giuliani will co-chair a newly-formed outside group that is devoted to promoting President Donald Trump’s agenda.

Gingrich said in an interview he would help to oversee Great America Alliance, an independent, pro-Trump political nonprofit. It will also be co-chaired by former New York City Mayor Rudy Giuliani, who, like Gingrich, was an early and outspoken Trump supporter.

The organization will advocate for Trump’s policy priorities, including his Supreme Court pick, which Trump says he will announce Tuesday evening.

“My interest is in communicating the things that he wants to get done,” Gingrich said. He pointed to economic and infrastructure as two areas where the group would focus some of its efforts. “We can be pretty effective,” he said.

Great America Alliance is one of several outside groups that will support Trump’s policies. Another group that formally launched on Monday, America First, will be overseen by two senior Trump campaign aides, Brad Parscale and Nick Ayers. A third organization, 45Committee, has begun airing TV commercials that promote Trump’s cabinet picks.

Great America Alliance will also be run by two Republican strategists, Ed Rollins and Eric Beach. The two previously led Great America PAC, a super PAC that spent over $22 million in support of Trump’s presidential candidacy.

In a memo, Beach outlined plans to spent around $80 million over the course of 2017 on a variety of anticipated policy battles. He left open the possibility that the group could pressure GOP members of Congress who opposed the president’s plans.

“Our organization will aggressively promote President Trump’s agenda and help make sure the promises made to the American people during the campaign are kept by Congress,” said Beach. “This will be our top priority and we will oppose all efforts to obstruct these goals, regardless of partisanship.”
