Sen. Elizabeth Warren, D-Mass., made a subtle change to her Twitter account Saturday that has some thinking it was a clue into her plans for 2020.

A Twitter bot that tracks lawmakers' changes to their Twitter accounts, Changes of Congress, first noticed that the liberal senator's campaign account handle had been tweaked to drop a reference to her home state of Massachusetts.

The handle, used to tag people on Twitter, was changed to "ewarren" from "elizabethforma."

Speculation began soon after on a slow news night.

Soon after the change was observed by the Washington Examiner, a second look showed the old Twitter handle, "elizabethforma," once again visible. The new handle led to a page saying that it does not exist. However, if a computer mouse hovers over the handle "ewarren," it previewed a link to the campaign page.

It is unclear if the change was made and then quickly undone, though some on Twitter appear to have caught the quick fix.

The Washington Examiner has reached out to Warren's office for comment.

Warren has multiple verified accounts. Her campaign account has 2.14 million followers, while her senator's account, with the handle "SenWarren," has 4.68 million.

Warren has so far only said she is thinking about running for the 2020 Democratic nomination. She told a Massachusetts crowd in September, "After Nov. 6, I will take a hard look at running for president."

That was a reference to the 2018 midterm elections. Since then, she has been relatively mum on her plans. She did fuel speculation in mid-October with a controversial DNA test to address questions about her past claims that she has Native American ancestry. There has been reporting on how she is ramping up a political machine for a run, including shopping for campaign headquarters space in Boston.

A large stable of Democrats are expected to compete for the nomination, including a number of current and former senators, governors, and mayors.
