Democrats will argue before a federal judge in New Jersey on Friday that Republicans are coordinating with GOP presidential nominee Donald Trump to intimidate voters.

The Republican Party says the charges are not true.

The legal challenge is one of several around the country filed by Democrats claiming Republicans and the Trump campaign are pushing supporters to intimidate and confront voters on Election Day.

Republicans on Thursday fought back against charges of wrongdoing before judges in Nevada and Arizona. Arguments will be heard on Friday in Ohio and in Pennsylvania on Monday.

The nearly identical legal challenges seek court orders intended to block volunteer GOP poll watchers from harassing people headed to the polls.
