WASHINGTON (AP) — Senators will launch a final round of questioning of Brett Kavanaugh today, but after a marathon 12-hour session, President Donald Trump’s nominee to the Supreme Court appears to have avoided any major missteps that could trip his confirmation.

So far, Kavanaugh does not seem to have changed minds on the Judiciary Committee, which is split along partisan lines. The judge left unanswered questions over how he would handle investigations of the executive branch and whether he would recuse himself if cases involving Trump under special counsel Robert Mueller’s probe end up at the court.

His credibility may face new tests by senators who are seeking to make public some emails and documents from his Bush White House years that are being withheld by the committee as confidential.

Trump says he’s pleased with his nominee’s televised performance, and Republicans are united behind him, eager to add a conservative judge to the court.

The questioning of Kavanaugh has carried strong political overtones ahead of the November congressional elections. Democrats lack the votes to block confirmation, but have been pressing Kavanaugh for his views on abortion rights, gun control and other issues. Protesters have added to the challenges for Kavanaugh, repeatedly interrupting proceedings.
