President-elect Donald Trump has suggested he wants to use “recess appointments” to confirm his Cabinet nominees when he takes office, a process that could allow controversial picks like former Rep. Matt Gaetz, R-Fla., and Robert F. Kennedy Jr. to avoid a contentious Senate confirmation process—but may be hard to implement in practice.

He is reportedly considering triggering an obscure constitutional provision that would allow him to force a recess over the objections of the incoming Republican Senate majority. The move would permit him to put any nominee in place at will.
