Ed Klein is one of Clinton's most trusted and relied upon legal counsels. He has explicitly warned Hillary Clinton to get a criminal lawyer, may be the best defense counsel, on board in her email controversy case. Klein has laid out his concerns about the wide exposure being received to her email controversy case that he presumes to be getting spirally out of control. He also warned her about implications in case she's indicted for mishandling classified documents on her private e-mail server and for lying under oath, said NewsMax.

Ed Klein has been Clinton's advisor and confidant for more than 30 years termed her email controversy case to be similar to John Dean of Watergate fame which may prove cancer on her candidacy. He also stated in a wide-range interview that he is used to have his advices on legal matters to be taken seriously and acted upon by the Clintons. However, although Bill Clinton had been extremely serious, Hillary Clinton was still acting as if it was only a political smear job by the oppositions. He has repeatedly stated that FBI email investigation could go in a dangerous direction if not dealt quickly and seriously.

"Hillary needs to secure the services of an expert legal counsel-preferably a big-league defense attorney from the Republican side of the aisle," the adviser said. "She needs someone to find out whether the FBI and Justice Department are likely to conclude that she's violated federal laws governing national security," said Klein in an interview to NY Post. He also stated that he expects the FBI investigators and Justice Department to wrap up the case much sooner than expected.

The keyword 'knowingly,' is the most important word in the whole investigation said LA Times. Clinton has repeatedly said that she did not knowingly send or receive emails that were marked classified, and that her use of a personal email server was not illegal or unauthorized.
