WASHINGTON -- Judge Sonia Sotomayor met with the newest member of the Senate Judiciary Committee this week -- Minn. Sen. Al Franken.
She's been through confirmation hearings before, but the one she'll face Monday will be unlike anything she's experienced.
Senators have already lined up witnesses.
Democrats will work to paint her as a mainstream judge, calling witnesses like former Bush political appointees and even New York City Mayor Michael Bloomberg, who ran as a Republican, but became an Independent.
Republicans are calling on Frank Ricci from New Haven, Conn. -- a white fire fighter whose reverse discrimination case was rejected by Sotomayor -- a ruling the Supreme Court recently overturned.
Charmaine Yoest, president of Americans United for Life, will be the principle pro-life witness.
In a statement, she says: "It's important for the American people to understand that the confirmation of Judge Sonia Sotomayor to the Supreme Court will dramatically shift the dynamics of the Court. Her record of activism in support of a radical pro-abortion agenda is clear and documented."
Pro-life group Operation Rescue demonstrated outside Kansas Sen. Sam Brownback's Topeka office this week.
"We are calling on Sen. Sam Brownback to use his political capital, not just to filibuster, but to lead a filibuster," said Randall Terry, founder of Operation Rescue.
Sotomayor has spent long hours preparing for the battle to come.
She's been reviewing her own writings and rulings. And for weeks, endured hours of mock hearings in which top lawyers grill her with tough questions likely to be asked by senators.
Appointing a judge to the Supreme Court for life is a heavy decision.
To prepare, Rev. Rob Schenck, president of Faith and Action, prayed over the hearing room.
"I anoint these doors in the name of the Father, and of the Son and and of the Holy Spirit," he said.
If confirmed, Sotomayor will become the first Hispanic and the third woman to serve on the High Court.
