Senator Elizabeth Warren has written a letter to Apple CEO Tim Cook, requesting information about Cook's discussions with the Trump administration regarding tariffs and any special tariff exemptions. According to a report by Bloomberg, Warren's letter suggests that Apple has been heavily influencing the Trump administration through a $100,000 donation to Trump's inauguration and Cook's attendance at the event. The letter references a recent Washington Post report on Cook's conversations with White House officials, including Commerce Secretary Wilbur Ross, about tariffs and their impact on iPhone prices. Warren's letter also mentions Trump's tariff exemptions for smartphones and other electronic products, noting that Apple appears to be the only company to benefit from most of these exemptions. The letter concludes with a series of questions for Apple, including the nature of Cook's discussions with the Trump administration, when Apple learned about the exemptions, and the value of any additional profits Apple may have gained due to the tariff exemptions.
