What does "whatever may have been holding up Kushner’s clearance" mean??

Also asked whether it was a violation of the emoluments clause in the Constitution for Trump to take to Twitter on Saturday to promote one of his money-losing Scottish golf courses, Nadler replied, “it certainly seems to be.” He also said Trump demanding that a security clearance be granted to son-in-law Jared Kushner over the objections of intelligence officials, as the New York Times reported last week, was an abuse of power.

“The president has a right to do a lot of things, but he can abuse his power in doing that,” Nadler said.

House Minority Leader Kevin McCarthy, also asked about the security clearance on ABC, said the president has the right to pick his own team and that Trump obviously wasn’t concerned about whatever may have been holding up Kushner’s clearance.

“They give you the pluses or the minuses, whatever the concerns are,” McCarthy said. “The president made the choice and he’s doing a good job at it.”
