Danney Williams, the man from Little Rock, Arkansas, who has claimed since the 1990s to be the black illegitimate son of former President Bill Clinton, will hold a press conference Tuesday at the National Press Club in Washington, D.C., to make an announcement his supporters characterize as a "bombshell that will rock Hillary's campaign."

Sources close to Williams who are planning the news event refused to divulge details of the announcement to WND.

Williams has demanded that Bill Clinton participate with him in a DNA test to verify his claim.

The conference will be hosted by a non-partisan coalition of civil rights, child-welfare and pro-life leaders.

Speakers, in addition to Williams, will include filmmaker Joel Gilbert and Dr. Randy Short, who heads the Brothers in Support of the Million Woman Movement, headquartered in Washington.

The Williams newser comes on the heels of FBI Director James Comey's announcement that the criminal investigation into Clinton's private email server has been resumed.
