"The Senate failed to pass an amendment to expand the FBI's National Security Letter powers and to make the ‘lone wolf’ provision of the Patriot Act permanent; however, the amendment will be voted on again later today," the release stated.
Earlier in the day, the EFF urged the Senate not to expand FBI’s authority.
"National Security Letters are a dangerous and unconstitutional power as is. This expansion must be rejected," the organization said.
On June 12, 29-year old US national Omar Mateen attacked the Pulse nightclub in Orlando, killing 49 people and wounding 53 others. Mateen pledged allegiance to the Islamic State terror group, which is outlawed in the United States, Russia and numerous other countries.
The incident prompted a number of bills to protect the United States from terrorist attacks and adjust existing gun regulations.
