CLEVELAND, Ohio (AP): Election Day is Tuesday, and lawyers for Democrats around the country are filing lawsuits claiming Republicans and the campaign of GOP presidential nominee Donald Trump are pushing supporters to intimidate and confront voters on Election Day.

The Associated Press reports that Trump has called on his supporters to act as “election observers” in certain areas of the country to help prevent fraud.

In Ohio, a federal judge today issued a temporary restraining order against Trump’s campaign and his friend and informal adviser, Roger Stone, barring them from harassing or intimidating Ohio voters during Tuesday’s election.

Attorneys representing the Democratic Party argued in five states that the GOP was coordinating with Trump to intimidate voters, accusations that the Republican Party says are not true.
