It might not take long for President Trump and his former chief strategist, Stephen K. Bannon, to clash for the first time since Bannon's departure from the White House.

Trump will address the nation in prime time on Monday and is expected to lay out a military strategy that includes deploying more troops to Afghanistan. If he does, Bannon and Breitbart News, the website he immediately resumed leading after his ouster on Friday, will not be happy.

Here's an excerpt from Breitbart's preview coverage:

One of Trump’s campaign promises that had helped him reach into new voting blocs had been his promise to reduce America’s presence abroad so as to put “America First.” …
Once Trump was in office, Bannon is believed to have been a key voice in the White House pushing for Trump to keep that promise to his voters.
But with a strong globalist contingent firmly embedded in the White House — including not only many Cabinet members but also members of Trump’s family — the Trump administration has been slowly moving more and more toward more intervention abroad.

In a second article, Breitbart's Joel B. Pollak wrote that “the president risks fumbling into the kind of intractable conflict he specifically promised his voters he would avoid.”

Charlie Spiering, Breitbart's White House correspondent, wrote in a third article that “before he was elected president, Donald Trump frequently expressed frustration with America’s longest war.” Spiering went on to recount the many times Trump tweeted messages like “let’s get out of Afghanistan” and “rebuild the U.S. first.”

It is not every day that Breitbart calls out Trump for hypocrisy — especially when he hasn't even broken a promise yet.

Plus, as The Fix's Aaron Blake pointed out, Trump “basically abandoned the withdrawal talk early on” in the presidential campaign. In a Republican primary debate, for example, he said, “You have to stay in Afghanistan for a while because of the fact that you're right next to Pakistan, which has nuclear weapons, and we have to protect that.”

Trump's strongest statements about leaving Afghanistan predated his entry into politics.

Breitbart, which often makes excuses for Trump, could easily give him a pass on Afghanistan. Assuming Trump says Monday what we think he will say, it won't be a huge surprise.

But Breitbart seems determined to hold Trump accountable for the overall, noninterventionist tone of his campaign, regardless of what he said about one particular country. Though the site's coverage of Trump is overwhelmingly favorable, on balance, it appears unwilling to look the other way if the president deviates from core promises, such as building a wall along the southern border, repealing Obamacare and avoiding foreign conflicts.

“With the globalists in Trump’s administration empowered, Americans can look forward to yet more blood and treasure being spent abroad on Rubik’s Cube foreign policy dilemmas like this — while problems at home get sidelined and underfunded,” Breitbart's Adam Shaw wrote on Monday.

Bannon said in an interview with the Weekly Standard on Friday that he told Trump, “I’ll always be here covering for you.” But he also said, “The Trump presidency that we fought for, and won, is over.”

With Bannon back at the helm, Breitbart might frame “the globalists” as the true villains. Trump makes the decisions, however, so there is only so much “covering” that Bannon can do.
