President Trump has talked about changing ’s tax treatment because he’s worried about mom-and-pop retailers being put out of business, Axios reported earlier on Wednesday.

The report comes at a time when tech stocks already under pressure after Facebook Inc acknowledged earlier this month that user data had been improperly harvested by a consultancy firm.

Trump has talked about using antitrust law to “go after” the because he is worried about mom-and-pop retailers being put out of business by Amazon, Axios reported, citing five sources it said had discussed the issue with him.

Trump also wants to change ’s tax treatment, the Axios report said, an issue the president raised publicly last year when he called for an internet tax for online retailers, even though Amazon already collects sales tax on items it sells directly to customers.

“The president has said many times before he’s always looking to create a level playing field for all businesses and this is no different,” said White House spokeswoman , when asked about the Axios report. “He’s always going to look at different ways, but there aren’t any specific policies on the table at this time.”

Trump has criticized Amazon over taxes and jobs in the past, without offering evidence. The president urging the use of antitrust law to selectively thwart a company would be unprecedented, according to Jeffrey Jacobovitz of the law firm Arnall Golden Gregory LLP.

Amazon’s stock, which fell as low as $1,386.17 on Wednesday, was last down 4.6 percent at $1,427.83. The shares have nearly quadrupled over the last three years.

Tech stocks have been under pressure after Facebook Inc acknowledged this month that user data had been improperly harvested by a consultancy.

“With Facebook and regulatory worries, the last thing nervous tech investors wanted to see was news that Trump is targeting Bezos and Amazon over the coming months as this remains a lingering cloud over the stock and heightens the risk profile in the eyes of the Street,” GBH Insights analyst Daniel Ives said.
