Washington (CNN) Jared Kushner's lawyer says the Senate Judiciary Committee is playing a "gotcha game" by accusing Kushner of not disclosing key documents -- including information about WikiLeaks.

Abbe Lowell, the attorney for President Donald Trump's son-in-law and senior White House adviser, said in an interview with CNN that the committee has "jumped the gun" with a letter to Kushner stating that they had not been provided documents about WikiLeaks, a "Russian backdoor overture and dinner invite," and communications with Sergei Millian, the president of the US-based Russian American Chamber of Commerce, who The Washington Post reported could be a source in the Trump-Russia dossier.

The backdoor overture cited by the committee refers to another of a series of Russian attempts in 2016 to try to make inroads with the Trump campaign and came by way of a West Virginia man who also sought to arrange for then-candidate Donald Trump to stop by an event on the sidelines of a National Rifle Association convention.

The email chain eventually made its way to Kushner, who rejected the idea, according to Lowell and sources familiar with the exchange. Kushner also warned others in the campaign about dealing with people who he believed exaggerated their connections.

"(I)f you look at the content of these emails, he's the hero," Lowell said of Kushner. "He's the one who's saying there shouldn't be any contact with foreign officials or foreign entities. That's what the Senate Judiciary Committee should pay attention to and not create some sort of partisan gotcha game."
