Washington (CNN) One of the seven House Democrats who had not made a public statement in support of launching an impeachment inquiry into President Donald Trump announced Wednesday he will back the House resolution formalizing the procedures of the investigation.

"While I disagreed with the initial decision to open the impeachment inquiry, it is clear that the investigation has confirmed information contained in the whistleblower complaint," Rep. Jared Golden of Maine said in a news release Wednesday. "For the good of our country and the public's understanding of the process, this investigation should no longer continue solely in a closed setting. Tomorrow, I'll vote to open up the House investigation to the American people."

House Speaker Nancy Pelosi announced earlier this week a House vote planned for Thursday to formalize the procedures of the impeachment inquiry into Trump and Ukraine, marking what will be the first time the House will go on the record on the proceedings.

Golden, though, cautioned in his statement that his support for the resolution "does not indicate that I am in favor of impeaching the president."

"As I've said from the beginning, I will continue to treat these allegations with the gravity they deserve, and I refuse to prejudge the outcome. While the investigation continues, I will remain committed to the work the people of my state sent me to Congress to do," he said.
