Hillary Clinton's presidential campaign revealed a new effort to enlist the growing number of Republicans and independents defecting to the Democratic nominee's cause on Wednesday.

Together for America, a division of the Clinton campaign, announced the addition of several former Cabinet members to its list. The campaign announced endorsements on Wednesday from former Commerce Secretary Carlos Gutierrez, former Housing and Urban Development Secretary Carla Hills, former Maryland Rep. Connie Morella, former Connecticut Rep. Chris Shays and former Director of National Intelligence John Negroponte.

"Americans are looking to the next president to help bring us together to tackle the big challenges facing the country and Hillary Clinton's bipartisan support is the latest proof that she can work across the aisle to make us stronger together," said John Podesta, Clinton campaign chairman, in a statement. "Hillary Clinton's experience and temperament make her a steady leader for this unique moment while Donald Trump is unfit, lacks the temperament, and is too dangerous to be in the Oval Office and the Situation Room."

The prominent Republicans and independents join former New York City Mayor Michael Bloomberg, Hewlett Packard CEO Meg Whitman, and former Treasury Secretary Hank Paulson as leading defectors to Clinton. On Tuesday, the Clinton campaign announced endorsements from two former Environmental Protection Agency administrators who served under Republican presidents — William K. Reilly of the first Bush administration and William D. Rucklehaus, who served Presidents Nixon and Reagan.

Trump addressed the news of leading Republicans and national security experts bypassing the GOP nominee for Clinton on Tuesday night, and told Fox News that, "These are terrible people."

"They're not endorsing because I don't want them," Trump said.
