By Luc Cohen, Tom Hals NEW YORK (Reuters) -Two U.S. judges on Tuesday extended temporary blocks on some deportations of Venezuelan migrants and signaled that President Donald Trump's invocation of a 1798 law historically used in wartime to speed up their removal from the United States may not survive judicial review.

A judge ruled Wednesday that the Trump administration must facilitate the return of a 20-year-old migrant, who was deported last month, because his removal violated a class action lawsuit settled last year.
