Yesterday The Daily Caller reported that the House Judiciary Committee has issued a subpoena to Glenn Simpson, the co-founder of Fusion GPS, the opposition research firm that commissioned the Steele dossier on the Trump campaign. The subpoena was issued on Friday.

The reason the Judiciary Committee wants to interview Mr. Simpson is that his testimony does not agree with the testimony of other witnesses in the investigation of the Christopher Steele dossier. Someone is lying, and the Committee needs to figure out who it is.

The article explains:

Simpson and Bruce Ohr met before and after the 2016 election to discuss dossier author Christopher Steele and Fusion GPS’s investigation into President Donald Trump’s possible ties to Russia. Simpson, who has been interviewed by three congressional committees so far, told the House Permanent Select Committee on Intelligence in November that he did not meet with Ohr until after the election.

But Ohr said in a congressional deposition on Aug. 28 that he met with Simpson in August 2016, four months before the election.

The article reports:

On Thursday, Simpson’s attorney, Josh Levy, told Goodlatte and South Carolina Rep. Trey Gowdy, the chairman of the House Oversight Committee, that Simpson would not appear for an interview, as the committees had requested last week.

“Part and parcel of this concerted effort by the President’s congressional allies has been a campaign of retaliation against the government’s whistleblowers, including our client Mr. Simpson, for their willingness to cooperate with US law enforcement and for their exercise of their constitutional rights to free speech and political activity as American citizens,” Levy wrote.

There is no way that Mr. Simpson is a whistleblower–he is part of a group that intended to end the presidency of a duly-elected President.
