They have temporary clearances. Certainly not a good situation late in the term, but not the sane as having no clearances.
But the temporary clearance is based on the premise that someone the President wants in the White House is presumed to be suitable during a clearance process that, according to press accounts, takes four to six weeks. Once negative information is revealed, the person should either be booted out, or someone at the top should make an affirmative decision that the revealed criminal record, bad debts, spousal abuse, Russian deals etc. aren't terrible enough to be disqualifying. Either way, "temporary" isn't supposed to be a work-around.
