I looked at Wikipedia:
(https://en.wikipedia.org/wiki/Economy_of_the_United_States#21st_century)
2013 GDP $16.785 trillion
2016 GDP $18.715 trillion
2019 GDP $21.439 trillion
18.715/16.785 = 1.115 and 21.439/18.715 = 1.146
So GDP grew 11.5% from 2013 to 2016. GDP grew 14.6% from 2016 to 2019. So the first 3 years of Trump the GDP grew more than the last 3 years of Obama. The main stream media got the claim wrong.
