During Sunday’s edition of “Last Week Tonight,” host John Oliver focused on Trump’s obsession with building a wall on the border between Mexico and the United States.

“This year, one particular wall has gotten a lot of our attention.”

After showing a series of clips where the candidate lovingly refers to the “beautiful wall” he intends to construct, Oliver said that Trump’s constant focus on the wall verged on sexual.

Setting aside the racism and xenophobia associated with the concept, Oliver looks more closely at the actual logistics of what Trump is proposing. What he discovers is that once again, Trump is utterly full of sh*t.
