Federal authorities investigating the pipe bombs that were sent to prominent Trump critics this week have focused their search on southern Florida, according to a report. Two people briefed on the matter told The New York Times on Thursday that investigators believe a number of the explosive devices were mailed from the area. According to CNN, authorities believe “several” of the packages passed through a processing and distribution center in Opa-locka, Florida. A total of 10 devices have been found across the country, including those sent to former President Barack Obama and former Secretary of State Hillary Clinton on Wednesday and packages sent to actor Robert De Niro and former Vice President Joe Biden on Thursday. An analysis of information collected by the United States Postal Service indicated that many of the packages were mailed from Florida.
