Brad Parscale, the Trump campaign's digital director, will be interviewed by congressional investigators looking into Russian interference for the first time this week, according to a report Sunday.

Parscale will be interviewed by the House Intelligence Committee on Tuesday, he confirmed to the Wall Street Journal, though a time has not yet been scheduled.

Parscale interviewed on CBS's "60 Minutes" earlier this month and revealed he made $94 million after President Trump won the election. He also revealed that staff from social media companies Facebook, Twitter, and Google spent time at the Trump campaign's office, working with him on how to increase outreach to possible voters, CNBC reported.

A number of current and former Trump aides are being interviewed by congressional investigators, as well as by special counsel Robert Mueller's team, as they look into Russian meddling in the 2016 election as well as possible ties between the Trump campaign and Russia.

Over the course of the investigations social media has become a leading concern.

Facebook announced in early September that it discovered the sale of $100,000 in ads during the campaign to accounts linked to a Russian company. Facebook turned over 3,000 ads connected to the Kremlin to Congress this month. The company previously had disclosed descriptions of the ads to Mueller.

Trump pushed back Saturday on the "fake news" reports about the money spent by the Russians on the Facebook ads.

"Keep hearing about 'tiny' amount of money spent on Facebook ads. What about the billions of dollars of Fake News on CNN, ABC, NBC & CBS?", he tweeted.

The Senate Intelligence Committee has invited Twitter, Facebook, and Alphabet, Google's parent company, to testify publicly on Russia-related matters on Nov. 1.
