After telling supporters that he would make a decision by the end of this month regarding a presidential run, The New York Times has reported that former Massachusetts Governor Mitt Romney will not be running in 2016.

Romney broke the news to a small group of advisers in a phone conference before explaining in another call to supporters that “After putting considerable thought into making another run for president, I’ve decided it is best to give other leaders in the party the opportunity to become our next nominee.”

Romney had showed interest earlier this month in seeking the Republican nomination again. During a meeting last week with advisers, the New York Times reported that support was offered to Romney but that support came short of actively encouraging a third run. According to NYT, enthusiasm from previous supporters about another run was “just not there.”

One of Romney’s former top aides, David Kochel, has taken a position as a strategist for potential presidential candidate Jeb Bush’s leadership PAC Right to Rise.
