The lawsuit from 19 Democratic attorneys general calls Trump's executive order an "unconstitutional attempt to seize control of elections."

Democrat-led US states filed a lawsuit challenging President Donald Trump’s executive order requiring major changes to the way Americans vote, escalating a legal showdown that started earlier this week with complaints filed by party leaders and nonprofits.

A group of 19 Democratic attorneys general is suing the Trump administration over its sweeping executive order targeting election rules and administration across the country, saying the president has no authority to make changes to federal elections.
