Democrats on Wednesday were angry with House Intelligence Committee Chairman Devin Nunes, R-Calif., for telling the press that Obama administration intelligence officials appear to have “unmasked” several Trump transition officials who were swept up in routine surveillance.

Nunes told reporters Wednesday that the new information he has “bothers” him, because it seems to show that officials revealed the identities of U.S. citizens caught up in routine surveillance of foreigners when they should have remained masked.
