Washington (CNN) Two red state Democrats facing re-election in 2018 announced on Friday that they oppose Brett Kavanaugh's nomination to the Supreme Court.

Sens. Joe Donnelly of Indiana and Jon Tester of Montana both came out against President Donald Trump's nominee the day after Christine Blasey Ford testified that Kavanaugh sexually assaulted her in the early 1980s -- allegations that Kavanaugh vehemently denied.

"I have deep reservations about Judge Kavanaugh's nomination to this lifetime position and ... we have been unable to get all the information necessary regarding this nomination, despite my best efforts," Donnelly said in a statement on Friday.

"While I would gladly welcome the opportunity to work with President Trump on a new nominee for this critically important position, if Judge Kavanaugh's nomination comes before the full Senate for a vote under these circumstances, I will oppose it," he said.

Tester put out a statement later in the day on Friday, citing a number of concerns with Kavanaugh's record as well as concerns over the allegations of sexual assault.
