Jared Kushner, President Donald Trump's son-in-law and senior advisor, plans to testify to the Senate intelligence committee on Monday morning that he "did not collude" with Russia or any other foreign government.

"I did not collude, nor know of anyone else in the campaign who colluded, with any foreign government," Kushner states in prepared testimony submitted to the committee and made public ahead of the meeting Monday. "I had no improper contacts. I have not relied on Russian funds to finance my business activities in the private sector."

Kushner's testimony will take place behind closed doors. The committee is one of several entities – including the FBI and several other congressional committees – investigating Russian interference in the 2016 election and the Kremlin's potential ties to the Trump team.

Kushner was also slated to appear before the House intelligence committee Tuesday.

Kushner's prepared remarks for the Senate committee indicate he will aim to address a raft of allegations concerning potentially improper contacts with Russian representatives, including why many of those interactions were not previously disclosed publicly or on a form to vet his security clearance until after being revealed in news reports.

His conversations last year with Russia's then-ambassador to the U.S., Sergey Kislyak, amounted to little more than an exchange of "pleasantries" and general statements of wanting to seek a "fresh start" in relations between the U.S. and Russia, he says.

"I had no ongoing relationship with the Ambassador before the election, and had limited knowledge about him then. In fact, on November 9, the day after the election, I could not even remember the name of the Russian Ambassador," Kushner's written testimony says.

Kushner, an investor and real estate developer, paints much of the imbroglio as a mix-up: his inability to recall conversations with prominent Russian figures a product of "thousands of meetings and interactions" during and after the election, his failure to note the meetings he did remember on his security form and in public statements a mistake stemming a frenzied campaign and miscommunications that caused the clearance form to be "submitted prematurely."

"Over the course of the primaries and the general election campaign," he writes in his 11-page testimony, "I ultimately worked with the finance, scheduling, communications, speechwriting, polling, data and digital teams, as well as becoming a point of contact for foreign government officials. All of these were tasks that I had never performed on a campaign previously."

The meetings with Kislyak and other Russian representatives were just a handful of what he later characterized to the FBI as "numerous contacts with foreign officials," he writes. None of those meetings were included on the security clearance form he says was accidentally submitted too soon, including meetings with "Jordan's King Abdullah II, Israel's Prime Minister Bibi Netanyahu, Mexico's Secretary of Foreign Affairs, Luis Videgaray Caso and many more."

However, in meetings with Russian representatives, he adds, "there were no specific policies discussed. We had no discussion about the sanctions imposed by the Obama Administration. At no time was there any discussion about my companies, business transactions, real estate projects, loans, banking arrangements or any private business of any kind."

He testifies that this includes what he observed during his brief participation in a meeting involving brother-in-law Donald Trump Jr. and a woman described as a Russian government lawyer who could provide damaging information on former Secretary of State Hillary Clinton. That interaction came to light in an explosive report earlier this month, prompting a new round of questions concerning potential Russian collusion with the Trump campaign.

Kushner says he did not previously disclose the meeting because he did not fully read the chain of emails leading up to the gathering, which described the lawyer's ties to the Kremlin.

"Reviewing emails recently confirmed my memory that the meeting was a waste of our time and that, in looking for a polite way to leave and get back to my work, I actually emailed an assistant from the meeting after I had been there for ten or so minutes and wrote 'Can u pls call me on my cell? Need excuse to get out of meeting,'" Kushner writes in his testimony.
