Sen. Claire McCaskill (D-MO) announced Friday that she will vote “no” on confirming President Donald Trump’s Supreme Court nominee Neil Gorsuch after publicly voicing her indecision on the subject early this week.

In a Medium post titled “Gorsuch: Good for Corporations, Bad for Working People,” McCaskill voiced her opposition to the nominee and explained why she will vote against him. She attributed her decision not to a party line vote, but one she came to after reviewing Gorsuch’s record, which she says shows a “stunning lack of humanity.”

“I cannot support Judge Gorsuch because a study of his opinions reveal a rigid ideology that always puts the little guy under the boot of corporations,” she said in the post. “He is evasive, but his body of work isn’t. Whether it is a freezing truck driver or an autistic child, he has shown a stunning lack of humanity.”

In the post, McCaskill painted Gorsuch as a champion of corporations and special interests, adding that he would not uphold Trump’s promise to help working people.

“The President who promised working people he would lift them up has nominated a judge who can’t even see them,” she wrote.

McCaskill’s announcement came just one day after two of her Democratic colleagues— Sens. Joe Manchin (D-WV) and Heidi Heitkamp (D-ND) — announced separately that they will vote next week to confirm Gorsuch. Many Democrats have publicly said they will vote no, citing either Gorsuch’s record or Republicans’ refusal to give a hearing to former President Barack Obama’s nominee Merrick Garland.
