Trump Mobile launches with the $47.45 "47 Plan," offering 5G service via major U.S. carriers, a U.S.-built smartphone.

Alongside the mobile business, President Trump has also launched his own meme cryptocurrency, while sons Eric and Donald operate their own data center cryptomining venture, ' American Bitcoin .' As president, Trump has created a strategic crypto reserve, pardoned crypto-related individuals, and relaxed enforcement of the sector.

The announcement represents another chapter in the unprecedented blurring of lines between Trump's personal business interests and his executive authority.
