Political career
Following the death of her father, Senator Renato Cayetano, due to liver cancer on June 25, 2003, several legislators, including senators, encouraged Pia Cayetano to run for office. As a result, she ran for a Senate seat in the 2004 elections under the support of President Gloria Macapagal Arroyo. Cayetano ran under the pro-Arroyo coalition called Koalisyon ng Katapatan at Karanasan para sa Kinabukasan (K-4). Initially, she was a virtual unknown to the electorate, but with the liberalization of political advertisements, she gained popularity with her TV advertisement as a runner, cyclist, and triathlete and as a new host of her father's TV program Compañero y Compañera for a short stint. She won in the elections, landing in the sixth position.
In 2006, she and her brother Alan had a fallout against President Arroyo and First Gentleman Mike Arroyo who called the Cayetano siblings “ungrateful”. This stemmed from allegations of then Taguig Pateros Rep. Alan that the Arroyos kept a secret multi-million-dollar German bank account. It was later revealed that the Arroyo government helped bankroll the Cayetano siblings' political campaigns, which Pia later admitted.
During the 112th Inter-Parliamentary Union (IPU) Assembly in Manila, Cayetano was elected president of the 10th Meeting of Women Parliamentarians during the sidelines of the annual meeting. On April 17, 2008, she was elected for a two-year term, president of the Committee of Women Parliamentarians of the Inter-Parliamentary Union (IPU) during its 118th General Assembly in Cape Town, South Africa. As the first Filipino and Asian to head it, she ran unopposed and took over from Uruguay's Mónica Xavier. This is the highest position held by any Filipino or Asian in the history of the IPU. In 2009, she criticized President Arroyo for a 1 million-worth dinner in New York City.
In the 2010 presidential elections, Cayetano backed the presidential bid of Manny Villar while she was running for reelection as a guest candidate under the Nacionalista Party. She won, landing in sixth place.
During this period, senators Pia Cayetano and Alan Peter Cayetano channeled a large amount of pork barrel funds to Taguig City where Pia Cayetano's sister-in-law Lani Cayetano was serving as mayor. Pia Cayetano and Alan Peter Cayetano were the biggest pork spenders in the Senate, having spent ₱277,006,092 and ₱256,700,000 of their pork barrel in 2012 as revealed during the pork barrel scandal investigations.
