White House Press Secretary Josh Earnest has been known to turn the sass dial up to 11 when commenting (or not) on Republican nominee Donald Trump. Earnest certainly put his sarcastic sense of humor to use Wednesday when asked about Trump's trip to Mexico to speak with President Enrique Peña Nieto. "It is not uncommon, of course, for the leading presidential candidates to make trips overseas," Earnest said, apparently referencing President Obama's own trip to Europe in 2008.
