Presumptive GOP nominee Donald Trump, referencing Sen. Elizabeth Warren (D-MA) as Pocahontas during his campaign rally Tuesday night, continued his criticism of the Massachusetts Senator on Twitter Wednesday.

Trump posted, “Goofy Senator Elizabeth Warren @elizabethforma has done less in the U.S. Senate than practically any other senator. All talk, no action!”

Out of Warren’s 42 tweets in the month of May, she’s tweeted to or about Donald Trump 38 times.
