Watch Trump’s journey: Wall to cave to 'perjury trap house'

07:35

President Trump caved in the largest battle of his Presidency over a border wall with Mexico and a Government shutdown, against the new Speaker, Nancy Pelosi. Ari Melber breaks down how Trump’s failed approach to the shutdown has revealed the cost of his hyperbole, false claims, inflated threats and lies. Melber examines how Trump not only blatantly lies about facts, but he also lies about what he will do as President and despite his lawyers saying they don’t want him to testify in the Russia probe because Mueller would spring a “perjury trap”, Trump is in trouble because of lies he told all by himself.
