Donald Trump and his congressional allies are escalating attacks on California's election system, demanding investigations into the state's slow vote count and accusing Democrats of rigging the results of this week's primaries. The 79-year-old president aired the accusations in a Truth Social post on Thursday night blasting California's election process as worse than that of a "Third World Country." Trump accused election officials of delaying the vote count in an attempt to manipulate the outcome. "They don't wait seven days to tell you who won, rigging the Election during each and every one of them," he said. The post came as Republicans ramped up attacks on California's election system following Tuesday's primaries. The results of the primaries for state governor and Los Angeles mayor have still to be called, with less than two-thirds of ballots counted by Thursday night.
