Updated 8:02 p.m. | The top Democrats on the House Intelligence and Judiciary committees said they will investigate the allegations that President Donald Trump directed his former attorney Michael Cohen to lie to Congress about negotiations in 2016 to build a Trump Tower in Moscow, as BuzzFeed News reported late Thursday.

House Intelligence Chairman Adam B. Schiff said the allegations underlying the BuzzFeed report are “among the most serious to date” and indicated he will direct committee investigators to probe them.

“The allegation that the President of the United States may have suborned perjury before our committee in an effort to curtail the investigation and cover up his business dealings with Russia is among the most serious to date,” Schiff tweeted late Thursday night. “We will do what’s necessary to find out if it’s true.”

Chairman Jerrold Nadler of the Judiciary Committee tweeted Friday morning that Thursday’s revelation about Trump ordering Cohen to lie to Congress fits into a “long pattern of obstruction” by the president.
