As the state's top election official, Reagan didn't have the ability to reject the official canvass from the 15 counties, despite acknowledging problems that led some voters to be incorrectly left off rolls. Maricopa County records show that five polling places in metro Phoenix still had voters in line after midnight, including one location where the final ballot was cast at nearly 1 a.m. Justice Department Voting Section Chief Chris Herron asked for information on 10 specific items including a description of how county election officials determined how many polling places were needed on March 22 and whether potential impacts on minority voters were examined. Maricopa County, with its 2 million registered voters, had 200 polling places in the 2012 presidential primary and 400 in 2008. ———

 PHOENIX (AP) — Gustavo Mendez waited four hours to vote in Arizona's presidential primary, marking his ballot just as poll workers brought out food for people stuck in line way past dark. Despite the investigation, Arizona Secretary of State Michele Reagan on Monday certified results of the presidential primary, which Donald Trump and Hillary Clinton won. Her certification of the results opens a five-day window for a challenge, something an attorney for Sanders is considering. Sanders lost to Hillary Clinton, but because Democrats allow delegates to their national convention proportionally, challenging the results could add to Sanders' numbers.
– Long lines at polling sites in Arizona's March 22 primary led Phoenix Mayor Greg Stanton to call the night a "fiasco"—and the Justice Department to now investigate whether there were civil rights violations regarding what Stanton called "unacceptably disparate distribution of polling locations," Reuters reports. The DoJ's civil rights division penned a letter Friday asking Maricopa County, the state's most populous, to determine if federal law was violated regarding, among other things, the number and location of polling sites (the county cut them from 200 to 60 in 2012 in an apparent bid to save money). The Justice Department's reason for this request: reports of "disproportional burden in waiting times … in some areas with substantial racial or language minority populations," the letter noted. Those waiting times were incredibly inconvenient: The AP notes that some voters waited nearly six hours, with the last vote cast at almost 1am at one site; polls had closed at 7pm, but voters already in line at that point were allowed to cast ballots. Poll workers even reportedly brought pizza to hungry voters. Maricopa County has until April 22 to respond to the DoJ's letter, which included 10 specific requests for information, including polling locations, procedures, and response to public backlash, the Arizona Republic reports. "We are going to gather the information … and we will make it public," the county elections director says. Despite these issues, Arizona's secretary of state certified the primary results on Monday, calling it for Donald Trump and Hillary Clinton, per the AP. (Here's hoping Wisconsin's big night Tuesday goes more smoothly.)
