Arizona Secretary of State Michele Reagan is set to certify results of the March 22 presidential primary that prompted lines of more than five hours after Maricopa County slashed the number of polling places.
Reagan is the state's top election official and will officially release the statewide vote courts and is expected to certify the results on Monday.
The official canvass will trigger an opportunity for candidates or individual voters to challenge the results. Lawyers for Democrat Bernie Sanders are considering whether a challenge is possible. Sanders' supporters believe he might gain additional delegates to the Democratic convention because many provisional ballots were thrown out in Maricopa County, but any challenge is legally difficult.
Democrat Hillary Clinton and Republican Donald Trump won statewide.
