Add T-Mobile to the list of Seattle-area companies in Sen. Elizabeth Warren’s crosshairs.

The 2020 Democratic presidential hopeful hasn’t pulled any punches in going after Amazon and other tech giants, saying that as president she would enforce antitrust laws and break up companies that have gotten too big.

Mega-billionaires such as Jeff Bezos and Bill Gates also get the Massachusetts senator fired up when she talks about the need for a wealth tax. Just this week she was trading tweets with Gates in a desire to explain to the Microsoft co-founder just what it might cost him if she won the White House.

From her official Senate Twitter account and from her campaign account on Wednesday and Thursday, Warren went after the FCC’s approval of T-Mobile’s merger with Sprint, a deal that will create a single $146 billion wireless carrier under the Bellevue, Wash.-based T-Mobile brand.

T-Mobile and CEO John Legere didn’t immediately wade into the Twitter battle. The company was too busy Thursday rolling out the “New T-Mobile” or “Un-Carrier 1.0” with initiatives meant to illustrate all that is good in its Sprint merger.

Before they even deal with Warren, the companies still face a multi-state lawsuit brought by attorneys general seeking to block the merger. The states, like Warren, claim that combining the third- and fourth-largest wireless carriers in the nation would hurt consumers and competition.
