Story highlights Jared Kushner is the President's son-in-law and also a key adviser

He met with and arranged meetings between campaign aides and Russian officials last year

(CNN) One of President Donald Trump's closest advisers, son-in-law Jared Kushner, has volunteered to testify before senators investigating ties between the Trump campaign and Russian officials, because of his role in arranging meetings between top campaign advisers and Russian ambassador to the US Sergey Kislyak.

The White House on Monday insisted Kushner's meetings were appropriate given his broad profile during the presidential campaign and transition.

"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 (Senate Intelligence) Chairman (Richard) Burr's Committee, but has not yet received confirmation," a White House spokesperson told CNN.

The Senate Intelligence Committee put out a statement from Burr and Vice Chairman Mark Warner confirming they were aware of Kushner's offer and said details were still being hammered out.

"The timing of Mr. Kushner's testimony is still being determined, but will only come after the committee determines that it has received any documents or information necessary to ensure that the meeting is productive for all sides," the joint statement said.
