The Trump administration will temporarily delay the processing of most refugees from 11 countries deemed to be high-risk, Reuters reported Tuesday, citing a memo written by top Cabinet officials to President Donald Trump.

The memo, which the administration provided to members of Congress on Tuesday afternoon, said the administration “will conduct a detailed threat analysis and review” for citizens of 11 “high risk countries.” In the meantime, it will “temporarily prioritize refugee applications” from other countries, the memo said.
