Another link suggested itself as I was researching this claim, and came up with a far more horrific figure. The estimates from a number of sources indicate that three times that amount has been spent in investigating the private email server of Hillary Clinton when she was Secretary of State. All the evidence I have seen appear to point out that other Secretaries of State had similar servers and, at the time she had her own server, the information in her communications was not classified as secret or even particularly sensitive. I did not see Dick Cheney under such scrutiny when he released the name of intelligence personnel, which is a felony.
What this means is that about $30 million of taxpayer money has been spent in an effort to indict someone, and it has as of now come to nothing.
