The former British spy who authored a controversial dossier on behalf of Donald Trump’s political opponents alleging ties between Trump and Russia reached an agreement with the FBI a few weeks before the election for the bureau to pay him to continue his work, according to several people familiar with the arrangement.

The agreement to compensate former MI6 agent Christopher Steele came as U.S. intelligence agencies reached a consensus that the Russians had interfered in the presidential election by orchestrating hacks of Democratic Party email accounts.
