BANGOR, Maine — U.S. Sen. Susan Collins said she learned about the Paris attacks Friday night at her home in Bangor.

Collins spoke with CBS13 by phone Friday, saying the attacks have all the “hallmarks of Islamic extremists” and calling the situation heartbreaking and a reality check for the U.S.

“We have to acknowledge the painful reality that ISIS, al-Qaida and other extremist Islamic groups are out to get us. That is not paranoia, that is the truth,” Collins said. “We would hand them a victory if we were to let them change our way of life.”

Collins said the most important thing the U.S. can do right now is share with France any intelligence information the U.S. might pick up on plots against them.

The senior senator also said she does not believe the attacks were made in retaliation for the presumed death of the Islamic State executioner who killed New Hampshire native James Foley.
