Poor Barack Obama can't catch a break with this guy around. All the historical import of this moment, all the lofty promises, and beautiful exhortations offered by the president.
But Biden, always eloquent, says it best. "This is a big, f***ing deal." (Content warning, obviously.)
The American people might use the same terminology, though in a slightly different way.
Update: I don't want to be too petty about this. Lord knows I enjoy Joe Biden for a laugh pretty frequently, but does the White House press secretary really need to endorse Biden's sentiment?
