Sen. Bernie Sanders (I-Vt.) is not ruling out a run for a soon-to-be-vacant Senate Finance Committee seat, which would add major heft to the progressive end of the dais.

“I do have some interest in it, yeah,” Sanders told reporters Wednesday, when asked if he’d be open to raising his hand for the seat that’s soon to open when Sen. Bob Menendez (D-N.J.) resigns in August. Menendez announced he’d step down earlier this month after a jury found him guilty on federal corruption charges.

The spot on the coveted tax writing panel will take on added significance next year, when most of the GOP’s 2017 tax cuts expire and a major tax battle is expected. Most of the individual tax cuts in that law will sunset without congressional action.

November’s election—where the GOP could take control of the Senate—will influence the partisan makeup of the Finance Committee.

Democratic Senate rules allow lawmakers to only serve on one of the three so-called Super A committees—Appropriations, Armed Services, or Finance. The party also informally prohibits two Democratic members from the same state from serving on the same panel.

That leaves a short list of potential candidates for the spot, which includes Sen. Cory Booker of New Jersey and Sens. Amy Klobuchar and Tina Smith of Minnesota.

Klobuchar has not expressed interest in the spot.

“The senator is a high ranking member of three committees—Agriculture, Commerce, and Judiciary—and is Chair of the Rules Committee, so she is not going to make a committee switch at this time,” a statement from Klobuchar’s office said.

Smith’s office did not respond to a request for comment.

Booker declined comment when asked by reporters about the vacancy, saying he had not yet spoken to Majority Leader Charles Schumer (D-N.Y.) about the potential opening.

Sanders, an independent who caucuses with Democrats, would join Sens. Elizabeth Warren (D-Mass.) and Sheldon Whitehouse (D-R.I.) on the panel, adding another champion for progressive priorities.

The Vermont lawmaker shares Democrats’ aims of taxing the highest-wealth Americans, and proposed calling for an annual tax on the top 0.1% of earners.

Sanders is the chair of the Senate Committee on Health, Education, Labor and Pensions, and would likely be able to keep the perch, though he may have to give up another post. He currently serves on the Environment and Public Works, Energy and Natural Resources, and Budget Committees.

Members who resign are replaced in the same way that members are added to committees at the beginning of Congresses, and nominations for assignments are made on a seat-by-seat basis.

Menendez’s departure also means the loss of a major tax voice on the Senate Foreign Relations Committee.

The New Jersey Democrat, convicted on charges that included accusations that he accepted bribes to act as an agent for Egypt, was a major advocate of tax treaties and strengthening tax ties with Taiwan.
