Former first lady Michelle Obama questioned the decisions of women who did not cast a ballot for Democratic presidential nominee Hillary Clinton in the 2016 presidential election, saying on Wednesday in Boston that they "voted against their own voice."

The comment came as Obama discussed her process for writing the book she’s working on during a question and answer session at Inbound, a marketing and sales conference. Obama was a keynote speaker at the event.

As Obama told the crowd that as she was working on her book, she reflected on why she was successful. She said success came because she stayed true to her “authentic self,” but feels that not everyone does the same, and used the recent election as an example.

“Quite frankly, we saw this in this election. As far as I’m concerned, any woman who voted against Hillary Clinton voted against their own voice," Obama said.

"What does it mean for us, as women, that we look at those two candidates… and many of us said, 'That guy? He's better for me. His voice is more true to me.' Well, to me that just says, you don't like your voice. You like the thing you're told to like," she added, referring to President Trump.

Obama campaigned for Hillary Clinton during the 2016 election, famously saying of Clinton’s critics, “When they go low, we go high.” Since leaving the White House, however, the Obamas have kept a relatively low profile in politics.

Obama did say today that despite her opposition to Trump's candidacy, she is hoping for the best from his administration.

“We want the sitting president to be successful, because we live in this country," said Obama. "He is our commander-in-chief. He was voted in. We may not like it, but it happened.”
