Washington (CNN) More than 300 former national security officials have come out in support of an impeachment inquiry into Donald Trump, arguing the President's actions in regard to Ukraine are a "profound national security concern."

"President Trump appears to have leveraged the authority and resources of the highest office in the land to invite additional foreign interference into our democratic processes," a statement signed by the officials and dated Friday reads. "That would constitute an unconscionable abuse of power."

The statement was released by the National Security Action, an advocacy group formed in 2018 by two former national security advisers in the Obama administration to oppose Trump's foreign policy.

The bulk of the statement's signees are former Obama officials, but the list also includes officials who have served in both Republican and Democratic administrations.

Former officials of the intelligence community, the State Department, the Department of Homeland Security, and the National Security Council staff are among the signees.
