President Donald Trump, in a Monday night tweet, appeared to tease a massive Immigration and Customs Enforcement operation that he said was poised to begin next week. “Usually major operations of this sort are considered ’law enforcement sensitive’ and a closely held secret, not telegraphed by the president,” Miroff said. “The Trump administration is doubling down on its efforts to block, bar and punish refugees for attempting to seek asylum in the United States,” a spokeswoman for the group said, Reuters reported. “These policies put the lives of refugees in great danger.”
