"Mr. Trump, I invited you here to thank us for what we've done for Flint, not to give a political speech," the pastor, Rev. Faith Green-Timmons, told the Republican presidential candidate.

"Oh OK, OK, OK, that's good," Trump replied. "Then I'm going to go back on to Flint."

The pastor's actions were met with some applause from the audience. Members in the crowd began asking Trump questions.

Trump replied to one, which couldn't be heard on the feed of the speech, saying "no, no, no, I never would."

The Manhattan billionaire promised to bring jobs back to Flint, saying that he heard a phrase that people used to build cars in Flint and couldn't drink the water in Mexico. Now, he said, the opposite is true.

Flint made national news earlier this year after the city's water supply was found to have toxic levels of lead, an effect of a decision by government officials to switch its water source.

Before being interrupted, Trump said Clinton "failed on the economy, just like she's failed on foreign policy."

"Everything she's touched didn't work out," he said.
