She was appointed NY solicitor general, the state's No. 2 legal position, by then-Attorney General Andrew Cuomo in 2007.
Another concern for Rice was she could face scrutiny for potential campaign finance violations if she ran for attorney general.
"I don't see a drastic change; I would see my role as continuing to look at the cases proposed", Underwood said.
Assembly Speaker Carl Heastie, D-Bronx, said lawmakers will do their due diligence before appointing Underwood or anyone else.
Almost every assemblymember and senator on the committee praised Underwood's credentials effusively; Democrat Senator Brad Hoylman called her a "real lawyer's lawyer".
Barclay, an eight-term Republican and deputy minority leader of the Assembly, said the special panel of lawmakers will review resumes of 16 candidates for the appointment and make recommendations to the full state Legislature.
Underwood went first and loomed large over the entire day of interviews.
"I'm not sleeping very much", she said with a laugh. Four women told the magazine Schneiderman, 63, physically and verbally abused them while they dated the attorney general, a Democrat who was running for a third four-year term.
The remaining six attorney general candidates, including Humbach, Diederich and Zapesochny, will interview Wednesday.
Though she said on the record she will not run for the office in 2018 elections, Underwood said she can bring stability to the position in the meantime.
Republicans who lead the state Senate favor Underwood, as does Gov. Andrew Cuomo.
"It's time to put people ahead of politics, and ultimately let the voters decide who their next attorney general will be", Flanagan said in a statement. Mike Gianaris, Public Advocate Letitia James, former gubernatorial candidate Zephyr Teachout and ex-U.S. Attorney Preet Bharara - opted to sit out the selection process.
