That account by FBI Director Christopher Wray challenged the White House assertion that Rob Porter's background "investigation was ongoing" and officials first learned the extent of accusations against him only last week, just before he abruptly resigned.
Wray's testimony marked the latest development in a scandal that has called into question the judgement of senior members of the White House staff, put new stress on the administration's already strained credibility with the public, and drawn accusations of tone-deaf handling of abuse allegations.
Privately, officials acknowledge that the public timeline offered last week -- that the administration first learned of the ex-wives' charges against Porter last Tuesday -- was flawed at best.
Several senior officials, including chief of staff John Kelly and White House counsel Don McGahn, were aware of the broad allegations against Porter for months, officials said.

Kelly found out after requesting an update on the large number of senior staffers operating without full security clearances, according to a senior administration official who spoke on condition of anonymity to discuss internal discussions.
Despite that, Porter took on an increasingly central role in the West Wing and was under consideration to serve as Trump's deputy chief of staff, two officials said.
White House Press Secretary Sarah Huckabee Sanders told reporters on Monday, "The White House had not received any specific papers regarding the completion of that background check." Yet Wray testified that the FBI sent the White House its preliminary report in March 2017 and its completed investigation in late July.
