President Donald Trump's eldest son and daughter were regularly briefed about a proposed Trump Tower in Moscow, Michael Cohen, the president's former longtime lawyer and confidant, testified Wednesday.

Cohen, testifying to the House Oversight Committee, said that Donald Trump Jr. and Ivanka Trump were involved in discussions about the deal, interactions he said were conducted in the regular course of business.

"Our goal was to get this project. We were interested in building what would have been the largest building in all of Europe," Cohen said. "After each communication" about the project, he continued, "I would report back" to Trump.

The testimony corroborates news reports detailing the Trump family's apparently close involvement in the Trump Tower deal. Discussions concerning the Trump Tower deal in Moscow continued through at least November 2016, but the project was ultimately scuttled. The interactions have remained a central focus of inquiries into Trump's interactions with the Russian government and potential collusion between the Kremlin and members of the Trump campaign.
