The former was transferred to the post of Interior Minister by the President in March 2001, and Aguad was named as his successor.

He was a vocal opponent of Resolution 125, which would have raised export tariffs on a range of agricultural raw materials, and advocated greater revenue sharing benefits for the provinces.

[2] His tenure as Mayor of Corrientes led to controversy, however, when Aguad took a US$60 million loan to cancel Cecacor bonds previously issued by the province.

The bonds, which had declined to junk status, could not ultimately be redeemed by the city government, and in 2009, Aguad was indicted for misfeasance related to their handling.

[4] Aguad was elected First Vice President of the Chamber of Deputies (the body's second-highest ranking post) by his colleagues in December 2010.
