Sen. Elizabeth Warren unveiled a plan Friday to break up massive technology companies such as Amazon and Facebook, the clearest proposal yet in the 2020 presidential race to limit the growth of Silicon Valley.

In a blog post, the Democratic candidate from Massachusetts wrote that she wants to make "big, structural changes to the tech sector to promote more competition." Those overhauls would include "breaking up" Amazon, Facebook and Google — companies that have come under scrutiny for both their protection of user data and consolidation of services such as e-commerce and digital advertising.
