MINNEAPOLIS (AP) — Minnesota Democrats are asking the state's Supreme Court to remove Republican presidential nominee Donald Trump from the ballot.

The state party filed a petition Thursday seeking to have Minnesota's secretary of state strip Trump and running mate Mike Pence for the general election. Democrats argue that the state GOP party erred in how it sent in Trump's name for a spot in the ballot.

State law requires political parties to select alternate electors at conventions. But Democrats contend those GOP alternates were chosen last-minute by party leaders to meet a looming deadline. The state's Democratic party says that invalidates the GOP's ballot submission.

Minnesota GOP party chairman Keith Downey did not immediately return a call seeking comment.

Early voting in Minnesota begins Sept. 23.
