President-elect Trump vowed Sunday that he would release long-classified government records on the assassinations of John F. Kennedy, Martin Luther King Jr. and Robert F. Kennedy.

Trump made the pledge to a crowd during his Victory Rally at Washington, D.C.’s Capital One Arena, which has a 20,000-seat capacity, telling supporters it is the beginning of an effort to increase government transparency.

“As the first step toward restoring transparency and accountability to government, we will also reverse the over-classification of government documents,” Trump said.

“And in the coming days, we are going to make public remaining records relating to the assassinations of President John F. Kennedy, his brother Robert Kennedy, as well as Dr. Martin Luther King Jr.,” he continued. “It’s all going to be released.”

Trump’s promise to also release outstanding documents related to civil rights icon Martin Luther King Jr. and former U.S. Attorney General Robert F. Kennedy, brother of former President John F. Kennedy, leaves questions as to how the president-elect will speed up the releases.
