WASHINGTON – Susan Rice, President Barack Obama's national security adviser, announced on Sunday that she would decide, following the mid-term elections next month, to run for the Senate from Maine in 2020 and overthrow Republican Senator Susan Collins.

Collins has cast a decisive vote to confirm Brett Kavanaugh at the Supreme Court, deeply disappointing for opponents of his appointment.

Speaking in New York at the New Yorker Festival, Rice said that Collins "put the party and politics ahead of its own principles" of supporting equal rights and legalized abortion . "I think that in any way I really regret having said, she has betrayed women across the country," Rice said.

Kavanaugh's confirmation was blocked by charges of sexual misconduct while he was in high school and at university, but Collins and others claimed to have been convinced by his energetic denials and an additional report by the FBI provides no evidence to corroborate these claims.

"What has moved me … is a feeling of indignation and frustration to see someone who pretends to be a moderate centrist, and someone who cares about it." Equal rights and rights of LGBT and Roe v Wade and all that kind of things, could not just decide to vote for Kavanaugh but do it in a way that does not take into account the concerns of many Americans and many Mainers, "said Rice. "So it's on this basis that I decided to think about it."

Kavanaugh's ancestry in the Supreme Court now gives the Conservatives an active majority that could curtail abortion rights and put an end to the expansion of LGBT rights.

Rice, a Democrat, had hinted at his interest in a Senate held in a tweet of a Friday word, answering "me" to an open question about who wanted to run against Collins. She then seemed to go back, saying that she "was not making any announcement".

Collins questioned Rice's connection to Maine, asserting Sunday in CNN's "State of the Union" that, although Rice's family has a home in Maine, "she's n & # 39; 39, not living in the state of Maine, everyone knows it. "

Rice, however, said that "her ties to Maine are long and deep." When she appeared on Sunday, she described the arrival of her Jamaican grandparents in that state in 1912, her annual summer visits that had begun during her childhood and the house she now owns. "In the last 20 years, I've owned a home in the state of Maine, so it's not completely crazy," she said.

Collins returned to Maine late Saturday after Kavanaugh was sworn in. She said Sunday that despite the presence of protesters outside her home in Bangor, Mainers' response was "extremely positive".

People angry at his vote have vowed to make him pay a political price. A crowdsourcing group claims to have pledged more than $ 3 million for its opponent in 2020.

Rice, who also served as United States ambassador to the United Nations to Obama, said he appreciated the excitement of his potential, but said people angry with Kavanaugh should focus on the mid-term elections.

"In the end, I'll think about it after the mid-term exams," she said.
