Colorado is suing President Donald Trump over an executive order establishing a national voter-eligibility list and imposing new restrictions on mail-in voting, which he calls "mail-in cheating". The state was one of the first states to embrace mail in voting, a method that has increased voter participation without increasing fraud. Colorado passed the Voter Access and Modernized Elections Act in 2013, which requires ballots to be mailed to every registered voter in the state and allows for same-day registration and voting, and expanded access to early in-person voting and election-day polling centers. Despite Trump's claims that these measures make voting easier, Colorado has joined with other states in suing Trump over the executive order. The lawsuit is part of over 60 lawsuits filed by Colorado Attorney General Phil Weiser against the administration over the past decade.
