Special Counsel Robert Mueller has hired 15 attorneys for his probe into Russia's involvement in last year's presidential election, seven of whom have donated to Hillary Clinton and other Democrats.

Thirteen of the appointees were identified Wednesday by The Washington Post.

The seven lawyers have donated a total of $60,787.77 to Clinton and other party candidates.

"In my view, prosecutors who make political contributions are identifying fairly strongly with a political party," William Barr, who served as attorney general under former President George H.W. Bush, told the Post.

In June, President Donald Trump slammed the ties of many of Mueller's appointees.

"I can say that the people that have been hired are all Hillary Clinton supporters," Trump told Fox News. "Some of them worked for Hillary Clinton.

"I mean, the whole thing is ridiculous, if you want to know the truth, from that standpoint."
