WASHINGTON, D.C. – Sen. Cory Booker of New Jersey is speaking out against Monday’s confirmation of school choice advocate Betsy DeVos as the next Secretary of Education, despite his history of supporting her mission.

“To all who are angry or frustrated about today’s vote confirming DeVos, please know: the vote may be over, but our fight must continue,” Booker tweeted Monday.

The message came with a video of the former mayor of Newark — and prospective 2020 presidential candidate — that played on the emotions of students, parents, and public school proponents who believe school choice options undermine the failing public education system.

“There’s a child, I think, that wonders if this country will prove itself true to them. They’re probably enduring some things I never had to endure. They are probably worried about their safety. They’re probably being put in a situation where they’re questioning their worth,” Booker said.

“My prayer is that that child knows, that even though it ain’t perfect and it won’t be easy, that they’re not alone. That there will be people fighting for them,” he continued before going on to quote Langston Hughes. “Because I was taught, in the words of a great poet: ‘There’s a dream in this land with its back against the wall … To save the dream for one, we must save it for all.’”

But many folks aren’t buying Booker’s feigned concern about DeVos’s confirmation, and several were quick to point out his hypocrisy.

“You’re such a fraud, you were on the same charter schools board as DeVos!” Twitter user gamer no tamago posted in response to the video, along with documentation proving the claim.  “Whatever DeVos does is your shared vision.”

“Wow, you’re super full of shit, Cory,” Erim Foster wrote, attaching a recent Washington Post story about Booker’s role in the school choice movement.

According to the Post:

When Sen. Cory Booker (D-N.J.) was mayor of Newark, he was a strong corporate school reformer, supporting choice and vouchers. He appeared at the May 2016 policy summit of DeVos’s American Federation for Children, which he called “an incredible organization,” and he urged the attendees to “stay faithful to the work we are doing.”

Another Twitter user posted a YouTube video of Booker’s comments at the AFC summit less than a year ago as evidence that the senator “worked with (DeVos) and repeated every one of her talking points.”

In that speech, Booker touted school choice initiates started during his tenure as mayor of Newark, and condemned the “institutions of failure” that plague the public school system.

“For me, this is not an academic discussion anymore. This to me is families that I know, neighborhoods, I’ve seen the kind of transformation that can be made. I see how kids who have no history of college in their families suddenly have the arc of their family’s trajectory changed as they’ve been liberated from what I call the imprisonment of institutions of failure and now have pathways to institutions of excellence all the way through college,” he told the AFC conference attendees.

Booker said the mission of the American Federation for Children, DeVos’s school choice advocacy group, “is aligned with the mission of our nation.

“This fight is so critical and so essential to who we say we are as a country,” he said.
