(CNN) Justin Amash, a former Republican-turned independent congressman from Michigan, said Wednesday that he stopped actively campaigning for his House seat in mid-February as he has been considering running for president as a libertarian.

"He has been discussing the potential campaign with his family, his friends, his team, and others, and a decision can be expected soon," Amash's campaign said in a statement.

His potential entry into the race comes after more than a year of refusing to rule out such a possibility.

If he does run, Amash would seek the Libertarian Party's nomination at their convention in Austin, Texas, which is currently set for the end of May. In 2016, Libertarian presidential nominee Gary Johnson, a former governor of New Mexico, was on the ballot in every state and won a little over 3% of the national vote.

While it is very unlikely a third-party candidate could win the presidency, a high-profile third-party contender has the potential to reshape the race.
