Courtroom drama marked the first week of a high-stakes federal trial underway in Kansas, the outcome of which could encourage or hinder tighter voter registration requirements across the country.
At the center of the lawsuit is Kansas Secretary of State Kris Kobach, one of Donald Trump's key backers on voter fraud and the president's unsubstantiated claims that millions of illegal ballots gave Hillary Clinton the 2016 popular vote.
Kobach led Trump's now-defunct election integrity commission.
