Donald Trump early Sunday said Hillary Clinton’s selection of Sen. Tim Kaine (D-Va.) as a running mate on the Democratic presidential ticket is “VERY disrespectful to Bernie Sanders and all of his supporters.”

The Republican presidential nominees also tweeted that it looks like the Vermont senator’s supporters will “fight,” adding that if they don’t, “there [sic] blood, sweat and tears was [sic] a total waist [sic] of time.” He later deleted that tweet and posted corrected text.

The Crooked Hillary V.P. choice is VERY disrespectful to Bernie Sanders and all of his supporters. Just another case of BAD JUDGEMENT by H!

Bernie Sanders started off strong, but with the selection of Kaine for V.P., is ending really weak. So much for a movement! TOTAL DISRESPECT

Looks like the Bernie people will fight. If not, their BLOOD, SWEAT AND TEARS was a total waste of time. Kaine stands for opposite!

{mosads}Clinton, the presumptive Democratic presidential nominee, announced her selection on Friday night. She appeared with Kaine at a rally in Miami on Saturday.

The Virginia senator is widely viewed as a “safe” pick, but the choice garnered criticism from Sanders for not being progressive enough.

The Democratic Rules Committee on Saturday voted overwhelmingly to reduce the influence of superdelegates in the 2020 presidential election after a deal was reached between Clinton and Sanders supporters.

Reports also surfaced late Saturday that Democratic National Committee (DNC) Chairwoman Debbie Wasserman Schultz would not speak this week at the Democratic National Convention in Philadelphia.

The development follows the leak of internal DNC emails that show an effort to undermine Sanders’s presidential campaign.
