He's had to amend his security clearance questionnaire several times to include meetings he's had with foreign nationals, including Russian agents.
As far as his decision to give Kushner a waiver of some kind, the president says he trusts his chief of staff, John Kelly, to make these decisions.
He complained that it had taken "months and months and months" for some of his staff members to be given their security clearances, despite the fact that some of them do not have complicated financial backgrounds - a factor that sometimes delays background investigations.
White House Press Secretary Sarah Sanders insisted Tuesday that Kelly's top-to-bottom review of security clearance procedures wouldn't have any effect on Kushner. The official said many staffers holding interim top secret or SCI clearances would lose them - but most don't need them for their day-to-day jobs.
Kushner is unlikely to obtain the full clearance as long as the special counsel's probe is ongoing, one of the sources said.
But question marks still loom over the future of Kushner's access to classified information. Kelly had known about the broad allegations against Porter for months, and initially moved to defend him.
Kushner's attorney, Abbe Lowell, also declined to elaborate when pressed by CNN, saying only via a statement that the new policy "will not affect Mr. Kushner's ability to continue to do the very important work he has been assigned by the President".
Kelly, in a memo released last week, had set a Friday deadline for halting access to top-secret information for those whose applications have been pending since June 1 or earlier.
Kelly's change only applies to clearances for access to the apex of the classification pyramid - top secret and sensitive compartmented information - not to lower-level clearances required to handle secret or confidential information. "I won't make that call".
Kelly, who threatened to resign after the scandal as not to tarnished his image as a man of order and discipline, is working to renew the process of security clearance, and one of his first steps is to revoke the provisional access permits to some high officials.
Porter's two ex-wives told DailyMail.com harrowing stories of spousal abuse, information that the Federal Bureau of Investigation had more than a year ago.
Combined with the initial surprise, Kelly's memo has fueled uncertainty in the West Wing about how the memo's directives will impact daily operations. It remains unclear how Kelly will limit access to highly classified information.
Trump made the comments during a joint press conference in the East Room of the White House with the Australian prime minister. Most of the White House staff can't get security clearances. Kelly expressed frustration with Kushner's access to classified material on an extended interim clearance, according to the official. That episode also prompted Kelly's crackdown on interim clearances. He also shoulders some of the White House's burden on matters touching Canada, China and Mexico.
