Former Democratic Governor of Vermont, Howard Dean says he suspects Trump Towers was wire taped, with good reason.
Still Democrats hit back over social media with the following tweets:

According to The Guardian reports:

"Presidents cannot legally order a wire tap operation unilaterally: federal agents and attorneys would have had to convince a federal judge either of probable cause of a serious crime or that the target of the tap was the agent of a foreign power.

However, the former British MP Louise Mensch reported in November that the Foreign Intelligence Surveillance Act (Fisa) court had granted the FBI a surveillance warrant of "US persons" to investigate possible contacts between Russian banks and Trump's associates. In January, the BBC reported that the Fisa court had issued its warrant in October".
