Judge Sonia Sotomayor is "within the mainstream" of jurists, a key Republican senator in her confirmation battle said Monday night.

"She's been a judge for 12 years, and when you look at her opinions, she's left of center but within the mainstream," Sen. Lindsey GrahamLindsey Olin GrahamDHS chief takes heat over Trump furor Overnight Defense: GOP chair blames Dems for defense budget holdup | FDA, Pentagon to speed approval of battlefield drugs | Mattis calls North Korea situation 'sobering' Bipartisan group to introduce DACA bill in House MORE (R-S.C.) said during an appearance on Fox News.

The comments come after a day in which Graham seemed to indicate some support for President Obama's choice to join the Supreme Court, marking a break with more conservative members of the GOP in the Senate -- including Senate Judiciary Committee Ranking Member Jeff SessionsJefferson (Jeff) Beauregard SessionsSessions: 'We should be like Canada' in how we take in immigrants DOJ wades into archdiocese fight for ads on DC buses Overnight Cybersecurity: Bipartisan bill aims to deter election interference | Russian hackers target Senate | House Intel panel subpoenas Bannon | DHS giving 'active defense' cyber tools to private sector MORE (R-Ala.).

Sessions said Sotomayor is "outside the mainstream" Monday morning during an appearance on CBS.

Indeed, "mainstream" was one of the top buzzwords during yesterday's opening day of hearings before the Judiciary Committee on Sotomayor's nomination.

Graham gave Sotomayor some other Republican cover yesterday when he told the federal judge she'll likely be confirmed by the Senate, barring a "complete meltdown."
