A bipartisan pair of senators are doubling down on their months-long push for Congress to authorize the war against the Islamic State in Iraq and Syria (ISIS) in the wake of last week's attacks in Paris.

"It's well past time that we move on this and hopefully the events of the past couple of weeks, the attacks that happened in Paris, the bombing of the plane, the other suicide bombings that have occurred, our commitment of new resources, will convince us all that it's time to act here in Congress," Sen. Jeff FlakeJeffrey (Jeff) Lane FlakeBiden nominates former Sen. Tom Udall as New Zealand ambassador Biden to nominate Jane Hartley as UK ambassador: report The Hill's Morning Report - Presented by Goldman Sachs - Voting rights will be on '22, '24 ballots MORE (R-Ariz.) said Tuesday.

Warren, Daines introduce bill honoring 13 killed in Kabul attack MORE (D-Va.) added that the "challenges of Paris" and other recent events underscore that lawmakers need to take up and pass an authorization for the use of military force (AUMF) against ISIS.

"This is a threat, and the president started military action for a narrow and limited reason, but that threat has mutated," he added. "Like a cancer, its grown and it is now affecting nations all over the world, and the question is how long will Congress continue to be silent." 

The two senators remarks come after ISIS formally claimed credit for the Paris attacks, which killed approximately 129 people. While Kaine and Flake have been outspoken advocates for lawmakers passing an ISIS-specific AUMF, the issue has failed to gain momentum in Congress.

The comments from leadership last week come after members of the Foreign Relations Committee have struggled for months to overcome policy and political hurdles on legislation authorize the military operation.

Corker admitted last week that he doesn't see Congress taking up an AUMF "any time soon."
Cardin added separately that he doesn't' "disagree with the assessments that have been given, that we don't see a path forward." 
While Democrats quickly suggested earlier this month that Obama's decision to send troops to Syria signaled that Congress must pass legislation authorizing the conflict, lawmakers quickly backpedaled and acknowledged that the president's decision was unlikely to add measurable momentum behind an AUMF's chances.
