Sen. Elizabeth Warren (D-Mass.) on Thursday night resumed her stream of disdainful tweets directed at presumptive GOP presidential nominee Donald Trump.

Warren, a fierce defender of the middle class, sent several tweets attacking Trump's meandering statements surrounding the federal minimum wage, and linked to a new PolitiFact article that calls a Trump claim "mostly false." The article examines Trump's back-and-forth opinions on the minimum wage and his assertion that Warren lied when she said he wanted to abolish it.

Trump, in fact, has called for the end of a federal minimum, telling NBC's Chuck Todd this month that states should decide a minimum wage, not the federal government. That position, as well as Trump's claim that wages are "too high," make clear "why working [people] can't make him the boss," Warren tweeted.

.@realDonaldTrump made clear he would abolish the federal minimum wage. One of a million reasons why working ppl can't make him the boss. — Elizabeth Warren (@elizabethforma) May 20, 2016

.@RealDonaldTrump trolls for votes & wants working ppl to believe he's for them. News flash, Donald: working ppl are smarter than you think. — Elizabeth Warren (@elizabethforma) May 20, 2016

Warren took to Twitter several times last week, seemingly unprompted, to chastise Trump's "dangerous" and "reckless" policy proposals, and his sexist treatment of women. She called out Trump's stances on student loan debt, financial industry regulation and Trump University.

Trump, in true Trump fashion, proceeded to mock Warren. He called her "Goofy Elizabeth Warren" and "one of the least effective senators" in history.

Warren's comments have drawn the attention of the Hillary Clinton campaign, including some who advocate Warren as a potential vice presidential running mate, according to a report from HuffPost's Sam Stein and Ryan Grim. Clinton and her aides were "thrilled to see Warren get under his skin," according to the report.

Warren ended her latest tweetstorm assuring Trump that his tirades wouldn't escape the notice of America's working class.

"News flash, Donald: working [people] are smarter than you think."

Editor's note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims -- 1.6 billion members of an entire religion -- from entering the U.S.
