"I spent two decades believing women and children who alleged abuse, even sometimes when no one else did", Rep. Trey Gowdy, R-S.C., a former prosecutor, said on CNN's "New Day" on Wednesday.
US President Donald Trump today denounced domestic violence, days after defending former White House Staff Secretary and his close aide Rob Porter, who was accused by his ex-wives of domestic abuse.
The White House was still working on Porter's security clearance at that point, according to White House spokeswoman Sarah Sanders.
Mulvaney said Trump and Kelly felt saddened and betrayed by the accusations that emerged against Porter.
Gowdy, who oversaw the House Intelligence Committee's months-long investigation into the 2012 terrorist attack on the U.S. Consulate in Benghazi, Libya, said the panel launched a probe of the Porter case on Tuesday night after Wray's testimony.
Wray is declining to elaborate on what information was passed on to the White House.
Some at the White House have blamed Chief of Staff John Kelly, adding that his job security remains uncertain.
House Speaker Paul Ryan was asked Wednesday about how the White House has handled the Porter allegations and whether Trump needs to publicly condemn domestic violence.
The White House has repeatedly claimed the background investigation was ongoing as the allegations of violence came to light, including photos of an ex-wife's facial bruising and graphic descriptions of abuse from another wife.
Porter resigned last week soon after the allegations surfaced. "I'll leave that to them", Ryan said.
Porter had been operating under a temporary clearance that have him access to some sensitive information without a final clearance.
Porter had been rising in Trump's inner circle and had been talking to Kelly about a promotion before his departure, according to a source familiar with the situation.
But FBI Director Christopher Wray told the Senate Intelligence Committee on Wednesday that the bureau, which investigates White House staffers for security clearances, completed its report on Porter last July and sent it to the White House - calling into question the Trump administration's evolving public account of its handling of the matter.
The scandals follow months of allegations by women about sexual harassment or abuse at the hands of powerful men in entertainment, business and politics. Trump has denied the accusations and has accused Democrats and the news media of orchestrating a smear campaign.
