President Donald Trump raged during a Thursday news conference in the Oval Office about the deal to make popular social media platform TikTok an American-owned company, saying the Federal Reserve didn't lower interest rates after the government published new economic data.

The Commerce Department released revised economic growth figures on Thursday, showing the U.S. economy grew at a staggering 3.8% pace between April and July. That was a significant improvement from the 0.6% growth rate recorded during the first quarter.

However, there were also concerning signs in the data. Business inventories fell by 3.4% and private investment fell by 5.1%.

Trump uncorked an outburst over the markets.

"This is the only country in the world where you announce great numbers and the stock market goes down," Trump said. "Because when you announce great numbers, they immediately want to take that success away by raising interest rates. Why can't they, when you announce great numbers, let them lower the interest rates so you can make numbers."

"There's no reason that every time we announce these record numbers, these numbers are way above projections from all those great geniuses; we knew this was going to happen," Trump said.
