Republican presidential nominee Donald Trump stirred the vote-flipping pot on Thursday, claiming on Twitter that he was getting “a lot of call-ins” about irregularities in Texas.

A handful of voters in at least three counties in Texas reported selecting the GOP ticket of Trump and running mate Mike Pence but then the Hillary Clinton-Tim Kaine Democratic ticket would show up instead, NPR reported.

Similar claims have also surfaced in North Carolina and Nevada, two states that The Rothenberg & Gonzales Political Report/Roll Call rates as Tilts Democrat. 

Local officials said the errors likely came from the user error, not glitches in the machines.

In typical Trump fashion, the candidate took to Twitter to voice his concerns and claims.

A lot of call-ins about vote flipping at the voting booths in Texas. People are not happy. BIG lines. What is going on?

Election officials in Louisiana and Georgia warned voters not to believe everything they read on social media and said they haven’t seen any problems.

Issues with voting machines are more likely to be about their age, as some are older than 10 years, Larry Norden, with the Brennan Center for Justice, told NPR.

“If you were actually trying to rig an election, it would be a very stupid thing to do, to let the voter know that you were doing it,” Norden said.
