She attacked him and made a fool of herself in doing so.
Seriously, her "you know that's not true" comment in response to the president stating that he created the greatest economy sounded like she was the DNC press secretary
Of course, the left says that the president's claims on this are false because we've experienced greater GDP growth in the past. But the president has NEVER used GDP growth to sustain his position on this matter. Rather, he has referred to things like the unemployment rate, stock market, etc., as he had to explain to Leslie during that segment. But partisan news organizations ignore this.
