The White House postponed a meeting Tuesday on the administration's approach to the Paris climate accord, blaming the schedules of staffers — Reince Priebus, Steve Bannon, Kellyanne Conway and Stephen Miller — traveling with President Trump. It did not provide a rain date.

Slated to attend the meeting, per various news outlets: Bannon and EPA Administrator Scott Pruitt, who both favor abandoning the pact, as well as Jared Kushner, who supports remaining in the accord, and Secretary of State Rex Tillerson, who has said the U.S. should maintain a "seat at the table" in global climate talks.

Why it matters: The eventual decision on whether to remain in the 2015 international pact is one of the biggest unresolved climate policy questions at the White House.
