The capital city's major will form an exploratory committee to look into a run for governor.
Luke Bronin said he'll file papers with the state on Thursday, according to a source.
He hopes to run on the premise that people have seen the way he's tried to tackle Hartford's financial woes.
Hartford has been teetering on the brink of bankruptcy, a story Channel 3's I-Team cataloged in its recent series Capitol in Crisis. The I-Team looked at how Detroit, MI dove into bankruptcy and is now thriving.
However, bankruptcy has been something Hartford has been staving off with help from the state.
Officials once said the capital city would run out of money in months without at least $40 million aid that was eventually included in the state budget.
Bronin also told Channel 3 during his mayoral campaign in 2015 that he'd stick around Hartford for at least a full term and then run for re-election because "you can't turn a city around in four years."
That changed late last month after he said people close to him have urged him to run for governor.
Channel 3 is continuing to work on this story.
