Agents involved in the Russia investigation asked Mr. Halper, an American academic who teaches in Britain, to gather information on Mr. Page and George Papadopoulos, another former Trump campaign foreign policy adviser.
However, Mr. Halper also had additional contacts with other Trump officials that have raised concerns about his activities. In one instance, Mr. Halper reached out to Sam Clovis, a Trump campaign aide; it was not clear whether Mr. Halper had the F.B.I.’s blessing to contact Mr. Clovis.
