ZURICH (Reuters) - Roche has had no contact with U.S. President Donald Trump’s personal attorney Michael Cohen, the Swiss pharmaceuticals maker’s Chief Executive said on Thursday.

“I have asked internally if we had any contact, and that is not the case,” Severin Schwan told Reuters when asked if his company had any dealings with Cohen.

The top lawyer at Roche’s cross-town rival Novartis quit on Wednesday over a $1.2 million contract he co-signed with Cohen, a deal Novartis’ ex-CEO also said was a mistake.
