A bad look for Trump, who walks out of a tough interview and repeats unproven claims that California's elections are rigged.

• Trump ended a Meet the Press interview with Kristen Welker after she pressed him for evidence that elections were rigged.
• He had no proof, then called the press and major networks "crooked" before walking off.
• He claimed California's elections are rigged, pointing to the slow Los Angeles mayor's race vote count.
• The slow count fuels suspicion, but slow counting is not the same as fraud.
• In LA, Nithya Raman pulled ahead of Spencer Pratt as late ballots came in, and Pratt is now crying foul too.

Outlook: The LA mayor's race looks headed for a Karen Bass–Nithya Raman runoff, with rigging claims likely to keep flying despite no evidence.
