Porter resigned Wednesday after being accused of abusing two ex-wives.
Just hours earlier, White House speechwriter David Sorensen became the second staffer to step down in a week after his ex-wife, Jessica Corbett accused him of physically abusing her during their two-and-a-half-year marriage.
"He says General Kelly is doing a great job and that he has full faith in him", Conway said on CNN'sState of the Union.
The claims were revealed on Tuesday amid questions that the White House was aware of the accusations for months because Porter was unable to get a security clearance after an Federal Bureau of Investigation background check uncovered a restraining order against him.
Porter-who resigned on Wednesday-is reportedly involved romantically with White House communications director Hope Hicks, for whom his second ex-wife, Jennie Willoughby, says she's anxious.
Porter's first wife said he kicked her and posted an image of herself with a black eye, which she says she received from Porter punching her.
Some complained that Donald F. McGahn II, the White House counsel, who learned last January that Porter was concerned about potentially damaging accusations from two ex-wives, had not been forthcoming enough about what he knew. He said very strongly yesterday that he is innocent.
On NBC's "Meet the Press", Trump aide Marc Short acknowledged the situation could indicate "a lack of communication between different elements in the White House". "And that's something I think the president ought to correct".
Maloney spoke with News 12 about why he says the Porter problem affects everyone, including his constituents in the Hudson Valley.
"Meanwhile the incredible cocoon of privilege and ego with which the President envelopes himself blinds him to the sheer horror of his statements in defense of Mr". Conway said she was "horrified, very shocked" to learn of the accusations against the Oxford-and Harvard-educated Porter because of her highly professional relations with him inside the White House. Shortly after that, McGahn informed chief of staff John Kelly that there could be problems related to Porter's security clearance.
The of now-former aide Rob Porter has dominated much of the news cycle this week.
