Five voters formally objected to former President Donald Trump’s newly-filed state nominating petitions Thursday on grounds that he helped engineer the fatal mob attack on the U.S. Capitol in 2021, adding Illinois to the national debate about Trump’s legal status as a presidential candidate.

In a filing obtained exclusively by WBEZ and the Chicago Sun-Times, the objectors want the State Board of Elections to disqualify Trump as a presidential candidate in Illinois’ March 19 primary and Nov. 5 general elections.

They argue that Trump violated a provision in the 14th Amendment that bars insurrectionists from holding public office, claiming he encouraged rioters to swarm the Capitol on Jan. 6, 2021 to block Democrat Joe Biden’s certification as president.

The state election board has openly questioned its authority to invoke the constitutional insurrection clause as a basis to sack a presidential candidate. The agency has suggested the dispute is one that Illinois’ courts or its legislature needs to resolve.

But the objectors believe the state elections board does have the legal standing to take on the question, though their arguments ultimately may land in a court of law, as similar disputes in other states involving Trump have.
