Federal investigators have monitored the phone lines of Michael Cohen, the longtime personal lawyer for President Donald Trump who is under investigation for a payment he made to an adult film star who alleged she had an affair with Trump, according to multiple senior officials and individuals with knowledge of the legal proceedings involving Cohen.
It is not clear how long the monitoring of phone calls has been authorized, but NBC News has learned it was in place in the weeks leading up to the raids on Cohen's offices, hotel room, and home in early April, according to one person with direct knowledge.
The calls are logged by what is commonly referred to as a pen register, which records the number of the phone that made the call and the number that received it, but does not record the contents of any conversation.
NBC News originally reported that Cohen's phone lines had been wiretapped, meaning a judge had given investigators approval to listen to phone calls. Three senior U.S. officials now dispute that, saying the monitoring of the calls was limited to a log of calls.
At least one phone call between a phone line associated with Cohen and the White House was logged, the person said.
Previously, federal prosecutors in New York have said in court filings that they have conducted covert searches on multiple e-mail accounts maintained by Cohen.
It is unclear how long this criminal action will go on by the feds vs. President Donald Trump and his entourage.
