Political allies of Senate Majority Leader Mitch McConnell have said the loss of Roy Moore in the Alabama race represented a major blow for Stephen Bannon.
Trump's former ally had come out and campaigned in support of Moore, despite allegations of sexual misconduct levelled at the Republican candidate.
At a recent rally, he told crowds there was a "special place in hell" for McConnell and other Republicans who should have known better than to not support him.
On Tuesday, it was revealed Moore lost the Alabama senate race to Democrat opponent Doug Jones, which McConnell's allies claim is a deep wound - potentially fatal - to Bannon.
The Hill is reporting the Majority Leader's allies are planning to use this to curb his influence over Republican voters.
The outlet is saying Republicans will now consider the true value of an endorsement from Bannon after his support for Roy Moore.
