All 535 members of Congress were invited to the event, hosted by the former U.S. vice president.

Talk about cold feet.

Not one Republican lawmaker showed up at Paramount and Participant Media's special Washington, D.C., screening of Al Gore's climate change documentary, An Inconvenient Sequel: Truth to Power, for Capitol Hill, organizers tell The Hollywood Reporter.

All 535 members of Congress were invited to the July 19 event, held less than two miles from the U.S. Capitol at the Newseum. Gore, who did a long stint in Congress before serving as U.S. vice president under Bill Clinton, hosted the gathering, which did succeed in drawing scores of Democrats.

Those attending included California's Nancy Pelosi, minority leader of the U.S. of Representatives; Sen. Bill Nelson; Sen. Jeff Merkley; former Sen. Barbara Mikulski; Sen. Jeanne Shaheen; Sen. Sheldon Whitehouse; Rep. Steny Hoyer; Rep. Suzanne Bonamici; Rep. Danny Davis; Rep. Debbie Dingell; Rep. Alan Lowenthal; Rep. Carolyn Maloney; Rep. Jim McGovern; Rep. Tom O’Halloran; Rep. Tom Suozzi; and Rep. Paul Tonko. Rep. Steve Cohen of Tennessee — Gore's home state — also turned out.

An Inconvenient Sequel, a follow-up to Gore's blockbuster 2006 documentary, An Inconvenient Truth, opens in select theaters Friday and arrives on the big screen as the Trump administration continues to dispute that man-made pollution is causing global warming.

On June 1, Gore, along with leaders around the globe, were stunned when President Donald Trump pulled the U.S. from the Paris Climate Accord.

Gore's film, which was produced and financed by Participant Media, follows him at the Paris Accord talks in 2015 as he plays the role of key negotiator, particularly with India, which initially balked at the emissions cuts the country would have to make. Paramount shifted its release plans in the aftermath of President Trump’s decision in an effort to gain a wider audience. Following the July 28 limited release, An Inconvenient Sequel will open nationwide on Aug. 4.

An Inconvenient Sequel directors Jon Shenk and Bonni Cohen, along with Gore, made last-minute changes to the doc to reflect the withdrawal from the Paris agreement.

The film held its world premiere at the Sundance Film Festival in January before playing at the Cannes Film Festival in May.
