Sen. Susan Collins announced on Tuesday that she does not intend to vote for President Donald Trump’s pick to lead the Department of Justice.

The Senate Judiciary Committee voted 12-10 along party lines in support of Acting Attorney General Todd Blanche to formally take the position on Tuesday, clearing the way for a Senate vote, potentially later this week.

Collins, a Republican, said she has “carefully reviewed” Blanche’s qualifications.

“While I believe Mr. Blanche is a capable lawyer, the Department of Justice has become increasingly political,” Collins said in a statement on Tuesday. “Mr. Blanche has taken several actions that have further eroded the department’s independence, and that is the basis for my vote to oppose his confirmation.”

She listed examples, including that Blanche “approved an order to shield the president, his sons, and the family business from IRS audits, protections unavailable to other American taxpayers,” his authorization of a $1.8 billion anti-weaponization fund, a promise that he “would seek to prohibit the mailing of abortion medication,” and the department’s attempt to indict Sens. Mark Kelly, D-Ariz., and Elissa Slotkin, D-Mich., under his leadership.

She also noted that more than 1,200 former DOJ employees have opposed his nomination.

The Maine Democratic Party was quick to criticize Collins following her announcement. MDP spokesperson Misha Linnehan said in a statement that Collins “waited until Todd Blanche’s confirmation was all but assured to conveniently announce her opposition.”

The Senate Judiciary Committee’s vote followed a deal struck late Sunday between Blanche and Republican Sens. John Cornyn of Texas and Thom Tillis of North Carolina, who had been threatening to block his confirmation over the settlement of Trump’s lawsuit against the Internal Revenue Service regarding the president’s leaked tax returns.

Cornyn and Tillis backed Blanche’s nomination after the Justice Department confirmed in writing that it wasn’t moving forward with a $1.8 billion fund to compensate Trump allies who believe they were prosecuted for political reasons, which the administration announced as part of the settlement.

After days of negotiations, Blanche issued an order Sunday evening confirming “beyond any doubt, that there is no fund.”

The full Senate could vote later this week on Blanche’s nomination. If all Democrats oppose him, Blanche can only afford to lose two Republican votes if Sen. Mitch McConnell of Kentucky, who was hospitalized after a fall, does not return before then.

At least two other Republican senators have not said if they will vote to confirm Blanche — Sen. Lisa Murkowski of Alaska and Sen. Bill Cassidy of Louisiana, who lost reelection this year when Trump endorsed one of his primary opponents. Both declined to comment when asked by The Associated Press how they will vote.

Sen. Angus King, I-Maine, “doesn’t issue statements ahead of votes,” a spokesperson said on Tuesday, noting the Senate has not yet scheduled one.

Blanche, Trump’s former personal attorney, took over as acting attorney general following Pam Bondi’s departure in April.
