After appearing on Rachel Maddow and Lawrence O’Donnell’s shows on MSNBC Tuesday night, David Cay Johnston tweeted that his wife and children received threatening phone calls.

Johnston, aDCReport.org journalist, said he received the two pages of returns through the mail from an unidentified source.

Johnston, who also authored the recent book “The Making of Donald Trump,” defended his decision to share Trump’s Form 1040 from 2005 on Maddow’s show, noting that he did not solicit them.

“There’s absolutely nothing improper about journalists, if you haven’t solicited something, getting it over the transom,” he said.
