WASHINGTON — President Trump started his day on Thursday publicly criticizing leaders of his own party for not advancing his legislative agenda, which the president called “so easy.”

Mr. Trump said he asked Senator Mitch McConnell, the majority leader, and Representative Paul Ryan, the House speaker, to include language about the debt ceiling in a recent Department of Veterans Affairs bill.

“They didn’t do it so now we have a big deal with Dems holding them up (as usual) on Debt Ceiling approval,” Mr. Trump said in a pair of Twitter posts.
