(CNN) Environmental Protection Agency chief Scott Pruitt, facing additional reporting about his many controversies, is "inching forward to the tipping point," a senior administration official said.

The official, describing the feeling within the administration towards Pruitt, wondered whether the EPA administrator would still hold his job as he could crop up in Democratic candidates' ads hitting President Donald Trump's "swamp."

Ultimately, the decision is with Trump.

White House deputy press secretary Hogan Gidley told reporters on Tuesday that Trump is looking into the "numerous reports" about Pruitt.

"The President feels as though Scott Pruitt has done a really good job with deregulating the government, to allow for a thriving economy, that's important to him, but these things matter to the President as well, and he's looking into those," Gidley said. "When we have an announcement, we'll make it."
