It is a crime for a campaign to accept help or anything of value from a foreign country. Yet, Kushner, Trump Jr, Manafort and others met with Russians to get dirt on Hillary Clinton. It was promised by the Russians to help Donald Trump win the presidency.
They should have immediately called the FBI and told them that Russia was offering to help their campaign. But these guys are completely immoral. In fact, Kushner said in a recent interview that he might not call the FBI if Russia offered similar help in the future!
