(AP Photo/Charles Rex Arbogast, File) For those wondering what it would take for Donald Trump to part ways with Corey Lewandowski, we have reached that juncture where the presumptive GOP nominee is shopping for a new campaign manager, reports the New York Times. “The Donald J. Trump Campaign for President ... has today announced that Corey Lewandowski will no longer be working with the campaign,” a Trump rep said in a statement Monday. “The campaign is grateful to Corey for his hard work and dedication and we wish him the best in the future." The reported cause of the split was infighting and Lewandowski's caustic relationship with many in the GOP leadership, as well as political media. "It's a total cage fight in there now," a source recently told Politico of the Trump campaign after another strategist was brought in in March. "Everywhere Corey looks, he sees a threat, so he’s trying to neutralize those threats." The firing was greeted with no small amount of glee in certain circles, with reporter Michelle Fields tweeting, "Hey @CLewandowski_ I hear @BreitbartNews is hiring." (More Corey Lewandowski stories.)
