As Ukraine Opens Probe Into Yovanovitch Surveillance, Foggy Bottom Remains Mute as a Mouse

Update 1:37 pm PST: Mid-day on Friday, CNN reports: After more than 48 hours of silence, Pompeo says State will investigate possible surveillance of ex-US ambassador

On January 14, we blogged about the Parnas documents indicating a possible surveillance of Ambassador Marie Yovanovitch while she was posted as U.S. Ambassador to Kyiv (see Parnas Materials: Surveillance of Ambassador Marie Yovanovitch in Kyiv).
According to NBC News reporter Josh Lederman, Robert F. Hyde reportedly dismissed the Parnas texts as “colorful texts” from when they’d “had a few pops way back when I used to drink” (see). When asked about Hyde’s claims of tracking Ambassador Yovanovitch, Lev Parnas in his first TV interview also said, “Well, I don’t believe it’s true.”  He added, “I think he was either drunk or he was trying to make himself bigger than he was, so I didn’t take it seriously.”
Since we have not heard anything from the State Department or Secretary Pompeo, are we to understand that the State Department is just taking their words that they’re joking around or drunk as claimed in their worrisome exchange? Given subsequent reporting on the Hyde character, that’s possible, of course. But if there was something there, anyone really expect that these individuals would admit to some nefarious intent publicly?
On January 16, Ukraine’s Ministry of Interior announced that it opened an investigation on the possible surveillance:

Ukraine’s position is not to interfere in the domestic affairs of the United States of America. However, the published references cited contain a possible violation of the law of Ukraine and the Vienna Convention on Diplomatic Relations, which protects the rights of a diplomat on the territory of the foreign country.

Ukraine cannot ignore such illegal activities on the territory of its own state.

Also on January 16, NBC News reported that the FBI paid a visits to Republican congressional candidate Robert Hyde’s Connecticut home and business.  FBI spokesperson told The Hill, “There is no further information that can be shared at this time.”  But as former DOJ staffer Matthew Miller points out, DOJ has had these messages for months. They’re investigating this claimed surveillance just now.
As of this writing, neither Pompeo nor the State Department has released any statement of concern on the possibility that one of its ambassadors was under surveillance for unknown reasons by people directly connected to Rudy Giuliani, the shadow secretary of state.
When State officials and Pompeo talk about protecting and supporting our diplomats in their town halls and chitchats, do they still say that loud with straight faces? Really, we’re curious.
