An Iowa student who attended Monday night’s Democratic presidential town hall event said the question he asked Hillary ClintonHillary Diane Rodham ClintonBiden slams Trump over golf gif hitting Clinton Overnight Cybersecurity: Equifax hit by earlier hack | What to know about Kaspersky controversy | Officials review EU-US privacy pact Overnight Tech: Equifax hit by earlier undisclosed hack | Facebook takes heat over Russian ads | Alt-right Twitter rival may lose domain MORE was submitted to no candidate in particular.

Conspiracy theories have been floated online suggesting the question at the CNN event was a plant — in part because of comments made by the student when he posed the question.

Brett Rosengren, who identifies as an undecided voter, asked the Democratic front-runner which past president inspired her. 

He stumbled on the question, accidentally calling Clinton “Sec. Sanders” — a reference to Sen. Bernie Sanders (I-Vt.), who is Clinton’s rival for the nomination.

“I can see why they gave you this question,” Rosengren then said, referring to Clinton.

After the forum, Rosengren said that the network didn’t provide him with the question, but that CNN decided to have him ask Clinton.

“It was my own question that I had submitted on Saturday night and directed towards any candidate,” Rosengren told US Uncut. “They chose that candidate to be Clinton.” 

The forum gave Democratic candidates’ one last chance to deliver their final pitches to voters in the Hawkeye State one week ahead of the caucuses, where Clinton and Sanders are locked in a tight race.
