Calling Trump a Liar, Using his Own Words
The problem with dealing with a pathological liar like Donald Trump is, even if you call him on it, he denies it.
The best way to deal with Trump lies is to use his own words against him and let the viewers decide.
MSNBC's Morning Joe did an excellent job of doing just that.
