The probe into Russia's interference in the presidential campaign reaches President Trump's son-in-law.

FOX's Jon Decker reports from the White House:

As part of their broad inquiry into ties between Trump campaign officials and Russian officials, Senate investigators plan to question Jared Kushner.

The Senate Intelligence Committee wants to question Kushner about meetings he arranged with the Russian ambassador, Sergey Kislyak.

A senior administration official tells FOX News that "Throughout the campaign and transition, Jared Kushner served as the official primary point of contact with foreign governments and officials. Given this role, he has volunteered to speak with the Committee."
