Roughly 90 intelligence officials, including the litany of former anti-Trump senior Obama officials, as well as some who served under Republican presidents, published an open letter in The Wall Street Journal late Sunday night, exuding their support for the unnamed whistleblowers. Those whistleblowers have accused President Donald Trump of a ‘quid pro quo’ for asking the Ukrainian president to investigate corruption associated with former Vice President Joe Biden’s son.

Andrew P. Bakaj, a former CIA officer and lawyer, as well as Mark S. Zaid, a national security lawyer, are representing the whistleblowers through the non-profit Whistleblower Aid. The pair confirmed this weekend that a second whistleblower has allegedly come   forward with first hand knowledge of the circumstances surrounding Trump and Ukrainian President Volodymyr Zelensky.

“This evening, the Wall Street Journal published an open letter from a group of about 90 former national-security officials who served under Democratic and Republican presidents, including Mr. Trump, supporting my client,” said Bakaj, on Twitter.

The founder of the non-profit CEO John Tye had told USA TODAY that the organization hopes “to protect the anonymous whistleblower’s rights including being free from retaliation, in addition to educating the public about the importance of whistleblowing.” However, the foundation was established under the Trump administration, sought whistleblowers against Trump and the attorney’s representing the whistleblowers have been accused by Republicans and opponents of being anti-Trump partisan “weapons being used against the president in an attempt to derail the Russia investigation,” said one former intelligence official, who asked not to be named.

The letter published in the Wall Street Journal includes the familiar names such as former Obama CIA Director John Brennan, former Director of National Intelligence James Clapper and President George W. Bush CIA Director Michael Hayden, among other notables.

“We are former national security officials who proudly served in a wide array of roles throughout the U.S. Government. We are writing about the Intelligence Community whistleblower’s lawful disclosure, which was recently made public. While the identity of the whistleblower is not publicly known, we do know that he or she is an employee of the U.S. Government. As such, he or she has by law the right—and indeed the responsibility—to make known, through appropriate channels, indications of serious wrongdoing. That is precisely what this whistleblower did; and we applaud the whistleblower not only for living up to that responsibility but also for using precisely the channels made available by federal law for raising such concerns.

A responsible whistleblower makes all Americans safer by ensuring that serious wrongdoing can be investigated and addressed, thus advancing the cause of national security to which we have devoted our careers. What’s more, being a responsible whistleblower means that, by law, one is protected from certain egregious forms of retaliation. Whatever one’s view of the matters discussed in the whistleblower’s complaint, all Americans should be united in demanding that all branches of our government and all outlets of our media protect this whistleblower and his or her identity. Simply put, he or she has done what our law demands; now he or she deserves our protection.”
