Ms Collins and Alaskan Senator Lisa Murkowski are moderate Republicans who have voted with Democrats in the past, making them possible swing votes when it comes to Judge Kavanaugh.
Dianne Feinstein was elected to the U.S. Senate in 1992, the original "year of the woman".
Back in 1991, however, the FBI did investigate sexual harassment claims against then-Supreme Court nominee Clarence Thomas. He admires it so much he's used it himself - many times. Diane Feinstein knew about this on July 30. This week, she called that play again. Especially when even if we defeat Judge Kavanaugh, we're just going to get someone else who's every bit as conservative?
Meanwhile, hundreds of alumnae of the secular private girls school that Kavanaugh's accuser attended have signed a letter supporting her and calling for an investigation of her allegations. An accounting of where and under what circumstances the boys met Christine Blasey Ford.
Mr Kavanaugh issued a fresh denial of the claims in a statement released by the White House last Monday.
"I take these allegations very seriously", the Delaware Democrat told MSNBC's "Morning Joe." "However, the Committee's stated plan to move forward with a hearing that has only two witnesses is not a fair or good faith investigation; there are multiple witnesses whose names have appeared publicly and should be included in any proceeding". But it's in among Senate Democrats, not Republicans. Instead they engineered an ambush, after Kavanaugh's hearing had already concluded, to try to drive him into a ditch before the vote. She said she was around 15 at the time and he would have been about 17.
Sarri underlines his discontent despite Chelsea sitting atop the league table
It should be no surprise, though, as Giroud's all round influence on games was visible at the World Cup. Hazard's scintillating hat-trick dominated Chelsea's 4-1 win over Cardiff on Saturday.
The rapid-fire response sparked a flare of tweets, including from actresses and liberal activists Debra Messing and Patricia Arquette, questioning how anyone could line up so many high school pals so quickly to speak up for someone they didn't actually go to school with. These men are not being forthcoming with what they know. This may be slightly overblown.
Timothy Avery, a former student who is now a postdoctoral research fellow, said he and many others admire her intellect and her kindness on the job.
Just days before the election in late October, Kavanaugh will be seated on the court, no doubt to a loud chorus of wails and gnashing of teeth.
Republicans are incensed that they have to go through this.
On Wednesday, Senator Jeff Flake - who had previously said he would not decide his vote until hearing both testimonies - also called on Prof Ford to accept the Senate's invitation.
