Congressional career 
House of Representatives 
At the Lower House, she authored, and co-authored about 280 bills (79 were enacted into laws) and proposed 101 local and national resolutions (20 were adopted). She became the Assistant Majority Floor Leader during the 8th Congress in 1987 and during the 10th Congress in 1995, becoming the first woman Assistant Majority Floor Leader in the history of the Lower House.
In the 1998 National Elections, she was elected senator under the opposition Laban ng Makabayang Masang Pilipino (LAMMP) banner. In the three years she was in office, Senator Aquino-Oreta filed 197 Senate Bills (authored and co-authored) and resolutions.
She participated in the impeachment trial of former president Joseph Estrada and was one of the senators who voted against the opening of the so-called "second envelope." After the vote, she was caught on camera doing a jig, which earned her the nickname "dancing queen" and offended some people. She apologized for the incident in a widely-broadcasted political advertisement. She subsequently ran for the Senate and was defeated. She has not successfully been elected to public office since.
