Phone records shared with the committee show that the younger Mr. Trump called a blocked number before and after calls with Emin Agalarov, a pop star in Russia whose family is friendly with the Trumps, to arrange the meeting, and again on the night of the meeting. But Mr. Trump’s memory was fuzzy when it came to who was on the other end of the calls.
When asked if he remembered details of the calls, Mr. Trump replied, “I don’t.”
Democrats have speculated that the blocked numbers could represent communications back and forth between him and his father. They are incredulous that Mr. Trump would have taken a meeting with Mr. Manafort and Mr. Kushner, two top campaign lieutenants, about damaging information on Mrs. Clinton without telling his father. The theory is given some credence by testimony from Corey Lewandowski, a top campaign aide, who told House investigators that Mr. Trump made use of a blocked number.
Finding a final answer, though, will likely be left to the special counsel. Democrats do not have subpoena authority, and Republicans have shown no interest in pressing for fuller records.
