President Donald Trump chose Brett Kavanaugh, a politically connected conservative judge, for the Supreme Court Monday, setting up a ferocious confirmation battle with Democrats as he seeks to shift the nation’s highest court further to the right.

With customary fanfare, Trump planned to unveil his choice on prime-time TV. A favorite of the Republican legal establishment in Washington, Kavanaugh, 53, is a former law clerk for retiring Justice Anthony Kennedy. Like Trump’s first nominee last year, Justice Neil Gorsuch, Kavanaugh would be a young addition who could help remake the court for decades to come with rulings that could restrict abortion, expand gun rights and roll back key parts of Obamacare.

With Kavanaugh, Trump is replacing a swing vote on the nine-member court with a staunch conservative. Kavanaugh, who serves on the Court of Appeals for the D.C. Circuit, is expected to be less receptive to abortion and gay rights than Kennedy was. He also has taken an expansive view of executive power and has favored limits on investigating the president.
