A Russian national asked to meet with then-candidate Donald Trump in May 2016, a request that is under scrutiny by the Senate Judiciary Committee as they seek more information from Jared Kushner.

The committee on Thursday asked for more information from Kushner, Trump’s son-in-law and White House senior adviser, concerning a “Russian backdoor overture and dinner invite.” The document request says the “dinner invite” concerned an email asking a meeting with someone by the name of Alexander Torshin and Maria Butina, reportedly Torshin’s assistant, an anonymous source told CBS News.
