British intelligence passed Trump associates' communications with Russians on to US counterparts

British and other European intelligence agencies intercepted communications between associates of Donald Trump and Russian officials and other Russian individuals during the campaign and passed on those communications to their US counterparts, US congressional and law enforcement and US and European intelligence sources tell CNN.

The communications were captured during routine surveillance of Russian officials and other Russians known to western intelligence. British and European intelligence agencies, including GCHQ, the British intelligence agency responsible for communications surveillance, were not proactively targeting members of the Trump team but rather picked up these communications during what's known as "incidental collection," these sources tell CNN.
