Steve Bannon, who recently vacated his post as White House chief strategist, has promised to light up Senate Majority Leader Mitch McConnell.

Steve Bannon, who recently vacated his post as White House chief strategist, has reportedly said that he would light up Senate Majority Leader Mitch McConnell. 
He made the remark during an interview with The Economist that was published on Friday. 
Bannon, who has since returned to Breitbart News as executive chairman, told the media outlet, “In the White House I had influence. At Breitbart, I had power.”
He further noted, “Mitch McConnell, I’m going to light him up.” 
The comment to take on McConnell comes amid growing tensions between President Trump and the Kentucky senator. 
Earlier this week, the New York Times reported, “The relationship between President Trump and Senator Mitch McConnell, the majority leader, has disintegrated to the point that they have not spoken to each other in weeks, and Mr. McConnell has privately expressed uncertainty that Mr. Trump will be able to salvage his administration after a series of summer crises.” 
Trump has recently made public comments that seem in line with the mutual animosity described by the Times. 
In a Thursday tweet, the president wrote, “The only problem I have with Mitch McConnell is that, after hearing Repeal & Replace for 7 years, he failed!" The president wrote in a Thursday tweet. "That should NEVER have happened!" 
“I requested that Mitch M & Paul R tie the Debt Ceiling legislation into the popular V.A. Bill (which just passed) for easy approval," Trump tweeted the same day. "They...didn't do it so now we have a big deal with Dems holding them up (as usual) on Debt Ceiling approval. Could have been so easy-now a mess!" 
McConnell has made some telling comments as well.
CNN notes that in an early August speech before a Kentucky Rotary Club, he said, “Our new president, of course, has not been in this line of work before. I think he had excessive expectations about how quickly things happen in the democratic process."
