Trump lies in front of Romanian president, who then contradicts Trump

During a joint press conference between Donald Trump and the president of Romania, the press asked if they discussed visa waivers. Trump lied and said "we didn't discuss it." But then the president of Romania said "Yes ... I mentioned this issue." Notice Trump's reaction when the president of Romania calls on his bullshit. Trump has no option but to say "definitely."

Question: Were visa waivers discussed?

Pres. Trump: "We didn't discuss it."

So Trump doesn't pay attention to the meetings he just had?
