How about the Ruskies in the Orbit of the Clintoon campaign who in effect paid over 100 million to her “foundation” to get a contract. Does that not count?? In fact, that was not just during a campaign, it is while she was a government official which last time I looked was the equal of BRIBERY...not so trumped up (pardon the pun) counter intelligence investigation.
There is no comparison between those whom people THINK might be suspicious and those who are acknowledged crooks and very suspicious.
Rubio is wishing that he had a campaign powerful enough to be spied on.
