He was Fuerza Democrática's presidential candidate for the 2006 national election.

He was Deputy from 1985 to 1990 and Senator from 1990 to 1992, when Alberto Fujimori dissolved the parliament.

Later that year he participated in a failed coup attempt, led by General Jaime Salinas Sedó.

In the 2006 presidential elections he was considered to be a very minor candidate and received 0.2% of the vote, coming in 13th place.

On December 20, 2017, at the Peruvian Congress, he defended President Pedro Pablo Kuscinsky from accusations of being morally unfit, his brilliant defence yielding a totally unexpected positive result, as there were not enough votes cast to impeach him.
