"I've thought about this race. I'm proud of the work I did in the legislature and outside of public office," Romanoff told 9NEWS.
Romanoff, who is currently a paid on-air contributor with 9NEWS, says that he has not yet made a decision on whether he will challenge Coffman in the 2014 midterm elections.
As he told POLITICO, Romanoff hasn't "made much secret of the fact that I'd like to return to public service."
"Most of the people I talk to believe Washington's not only broken, but can't be fixed. I think they're only half right," Romanoff told 9NEWS.
In 2012, Coffman won re-election in a redrawn 6th congressional district made much more competitive by redistricting.
Ultimately, Democratic challenger Joe Miklosi's campaign was unable to gain much traction against the incumbent.
Romanoff staged an unsuccessful bid for US Senate in 2010. The race was ultimately won by fellow Democrat Michael Bennet.
Initial reports of Romanoff's interest in a potential run drew quick pushback from Republicans, who criticized Romanoff for not currently living in the 6th district, and also for selling his Wash Park home in 2010 in a last-ditch effort to topple Bennet.
"The real question is what will Andrew Romanoff auction off this time around to pay for his campaign? The last thing Congress needs is more people like Andrew Romanoff who can't even balance their own budgets," NRCC spokesman Tyler Houlton said.
