DENVER (AP) — The campaign to use the U.S. Constitution’s “insurrection” clause to bar former President Donald Trump from running for the White House again enters a new phase this week as hearings begin in two states on lawsuits that might end up reaching the U.S. Supreme Court.

A weeklong hearing on one lawsuit to bar Trump from the ballot in Colorado begins Monday, while on Thursday oral arguments are scheduled before the Minnesota Supreme Court on an effort to kick the Republican former president off the ballot in that state.
