NEW YORK — His inauguration less than three weeks away, President-elect Donald Trump is raising new doubts about the nation’s intelligence community, tweeting fresh criticism at the same people who will help inform his most sensitive decisions once he takes office.

Trump charged Tuesday on Twitter, without evidence, that the timing of an upcoming intelligence briefing on suspected Russian interference in the 2016 election had been delayed. “Perhaps more time needed to build a case. Very strange!” he wrote, using quote marks around the word “intelligence.”

Trump’s tweet, in line with repeated criticism of his nation’s intelligence leaders, caused confusion among intelligence officials, who said there was no delay in the briefing schedule.

The fresh clash came as Trump took further steps to fill his Cabinet and key White House positions, with his attention shifting toward the challenges of governing.

Trump’s plans for repealing President Barack Obama’s signature health care law are expected to be the focus as Vice President-elect Mike Pence and secretary of state choice Rex Tillerson meet with top Republicans on Capitol Hill today.
