New Jersey Democratic Sen. Cory Booker broke from his party when he refused to endorse their call for the White House to revoke President Donald Trump’s son-in-law Jared Kushner security privileges. It also turns out that the potential 2020 White House contender received large sums of money from Jared Kushner and his family.

When reports broke out about Kushner’s attempt to set up a secret back-channel with Russia, the Democratic National Committee called for his security clearances to be taken away. Rep. Adam Schiff, the senior Democrat on the House Intelligence Committee, asked for a review of Kushner’s security clearances as well.

During an interview with CNN on Sunday, Booker would not support these calls.

“I think we need to first get to the bottom of it. He needs to answer for what was happening at the time. It raises very serious concerns for me. And that could be a potential outcome that I seek, but I want to understand, at least hear from Jared Kushner, as well as the administration, about what was exactly going on there,” the New Jersey Senator said.

When asked about his feelings about impeaching Trump, “I’m not going to rush to impeachment.”

PoliticalMoneyLine.com compiled data that show Kushner and some of his family members gave Booker’s Senate campaign over $41,000 in 2013. Ivanka Trump also hosted a fundraiser for the New Jersey senator.
