An intelligence report by the Department of Homeland Security contradicts the White House’s assertion that immigrants from seven Muslim-majority countries pose a particular risk of being terrorists and should be blocked from entering the U.S.

The report is the latest volley in a struggle between intelligence officials and the Trump administration that has rippled across several agencies. Some officials have critiqued administration policies, while the president and senior members of his staff have accused officials of leaking information to undermine his administration and the legitimacy of his election.

The report, reviewed by The Wall Street Journal, came from Homeland Security’s Office of Intelligence and Analysis. It said that its staff “assesses that country of citizenship is unlikely to be a reliable indicator of potential terrorist activity.” The White House on Friday dismissed it as politically motivated and poorly researched.

The compilation and disclosure of an intelligence report so directly at odds with top White House priorities marks an unusually sharp rupture between the administration and career public servants. It also underscores the difficulty President Donald Trump has had in converting his confrontational and bombastic campaign rhetoric into public policy.

The Trump administration is seeking to enforce an executive order blocking immigrants from the seven countries, which it has portrayed as based on nationality and security factors, and not religion. Mr. Trump is expected to issue a new order next week after federal courts blocked his first attempt to temporarily halt immigration and prohibit refugees from entering the country.
