Republicans lay legal groundwork for election challenges

In Arizona, one of seven competitive U.S. states that are expected to decide the 2024 presidential election, an advocacy group founded by Donald Trump adviser Stephen Miller is advancing a bold legal theory: that judges can throw out election results over "failures or irregularities" by local officials.

The lawsuit by the America First Legal Foundation, a conservative advocacy group, says the court in such cases should be able to toss the election results and order new rounds of voting in two counties in Arizona, where Democratic candidate Vice President Kamala Harris is leading Trump in the polls by a razor-thin margin.

The Republican National Committee says it is involved in more than 120 lawsuits across 26 states, in a strategy that some legal experts and voting rights groups say is meant to undercut faith in the system.
