WASHINGTON (Reuters) – U.S. Senate Democrats plan to hammer President Donald Trump’s Supreme Court nominee Brett Kavanaugh over his views on abortion and presidential power in hearings starting on Tuesday, but the conservative judge looks likely to be confirmed.

Trump’s fellow Republicans hold narrow majority control of the Senate so they can approve Kavanaugh if they stay united. So far, there were no signs of defections, with the Senate likely to vote by the end of the month.

The hearing, expected to last four days, gives Democrats a chance to make their case against Kavanaugh ahead of November’s congressional elections.

“There will be sparks at this hearing. Sparks will fly, and there will be a lot of heat,” Democratic Senator Richard Blumenthal, a member of the judiciary committee that will convene the hearings, said on Friday.

Trump nominated Kavanaugh, 53, to replace Justice Anthony Kennedy, who announced his retirement on June 27 at age 81. He is Trump’s second nominee to a lifetime appointment to the nation’s highest judicial body. Trump last year appointed Justice Neil Gorsuch, part of his push to make the courts more conservative.
