President Donald Trump’s repeated Twitter attacks on Amazon have already dented the e-commerce giant’s stock price. But if he really wants to hammer the company and its ultra-billionaire CEO Jeff Bezos, the president has some tools at his disposal — using the government's spending and regulating powers. Here's a look at the threats the company may face if President Trump follows up his words with action:

1. Postal rates
2. Cloud computing
3. Antitrust
4. State-level scrutiny

Alexander Tayler, the acting CEO of Cambridge Analytica, defended the firm saying, "As anyone who is familiar with our staff and work can testify, we in no way resemble the politically motivated and unethical company that some have sought to portray. Our staff are a talented, diverse and vibrant group of people." Tayler served as the company's chief data officer in 2015 when Facebook first raised concerns that Cambridge had gained access to the user data via British academic Aleksandr Kogan, in violation of the social network's terms of service.

An advocacy group known for challenging the tech industry on privacy called on the Federal Trade Commission Thursday to investigate media reports that Uber could identify specific iPhone devices even after users deleted the ride-hailing app. California-based Consumer Watchdog alleged that Uber’s practice would be considered “unfair or deceptive” to its users and therefore violates a statute in the Federal Trade Commission Act designed to protect consumers from substantial and avoidable harm.

The nonpartisan group also asked Acting Chairman Maureen Ohlhausen and Commissioner Terrell McSweeny to determine whether Uber engaged in similar tactics on Android devices and scrutinize whether the company is abiding by its own privacy policies. “They have a track record of not paying any attention to the rules. That’s why it’s important, no matter what they’ve done with Apple, for the FTC to act,” said John M. Simpson, Consumer Watchdog’s privacy project director.
