Phone calls between President Donald Trump's personal attorney, Michael Cohen, and the White House are being monitored by the Federal Bureau of Investigations, according to a report.

Cohen's phones are being monitored through a log of which numbers it connects with, the report says. President Trump and Cohen have had at least one conversation since Cohen's offices were raided in connection to an alleged payment the attorney made to a porn star who says she had an affair with Trump.

The report says the phone monitoring was approved by a judge weeks prior to the April 9 raid on Cohen's house in New York City. In the raid, authorities seized files related to the alleged payment Cohen made to Stormy Daniels for $130,000. 

The money was allegedly to pay her to keep quiet about the affair she says she and Trump had in 2006.

An earlier report said Cohen's phones had been wire-tapped, but that was found to be false.
