President Donald Trump lashed out against Amazon on Monday, saying the US Postal Service is its "delivery boy."

"The Amazon Washington Post has gone crazy against me ever since they lost the Internet Tax Case in the U.S. Supreme Court two months ago," Trump tweeted. "Next up is the Post Office which they use, at a fraction of real cost, as their "delivery boy" for a BIG percentage of their packages."

Trump has argued that Amazon takes advantage of the postal service, which he claims is losing money from the e-commerce giant. But the post office had been slipping into the red since before the rise of Amazon and is not funded directly by taxpayers.

Part of Trump's frustrations toward Amazon seem to associated with its chief executive officer Jeff Bezos owning the Washington Post. The tweets against came after a weekend of critical news reports on the Trump administration.

"In my opinion the Washington Post is nothing more than an expensive (the paper loses a fortune) lobbyist for Amazon," Trump tweeted. "Is it used as protection against the antitrust claims which many feel should be brought?"

Shares of Amazon fell about 1% to $1,796.20 following the tweets.
