President Trump on Monday said in a pair of tweets Monday the whistleblower who filed the complaint that set off the House impeachment inquiry must "testify to explain why he got my Ukraine conversation sooo wrong" and that they must be identified "to determine WHY this was done to the USA."

Adam Schiff now doesn’t seem to want the Whistleblower to testify. NO! Must testify to explain why he got my Ukraine conversation sooo wrong, not even close. Did Schiff tell him to do that? We must determine the Whistleblower’s identity to determine WHY this was done to the USA.
Democrat’s game was foiled when we caught Schiff fraudulently making up my Ukraine conversation, when I released the exact conversation Transcript, and when Ukrainian President and the Foreign Minister said there was NO PRESSURE, very normal talk! A total Impeachment Scam!

Why it matters: House Intelligence Chairman Adam Schiff (D-Calif.) on Sunday said that the committees investigating President Trump and Ukraine may not need testimony from the whistleblower, which could unnecessarily expose their identity and threaten their safety.

  • The White House released a rough transcript of the July 25 call between Trump and Ukraine President Volodymyr Zelensky.

What they're saying: "Our primary interest right now is making sure that that person is protected. Indeed, now there’s more than one whistleblower, that they are protected,” Schiff said.

  • When Trump similarly told reporters last month that "we're trying to find out" the identity of the whistleblower, their attorney Andrew Bakaj tweeted that his client is "entitled to anonymity. Law and policy support this and the individual is not to be retaliated against. Doing so is a violation of federal law."

Why it matters: When the Facility for Rare Isotope Beams begins experiments later this spring, physicists from around the world will use the particle accelerator to better understand the inner workings of atoms that make up all the matter that can be seen in the universe.

UK government: Kremlin has plan "to install pro-Russian leadership" in Ukraine

The United Kingdom's Foreign Secretary on Saturday night said the government has "information that indicates the Russian Government is looking to install a pro-Russian leader in Kyiv as it considers whether to invade and occupy Ukraine."

Driving the news: U.S. National Security Council spokeswoman Emily Horne called the intelligence "deeply concerning" in a statement to Axios. The Biden administration has said Russia is actively manufacturing a pretext for invasion and warned that Putin could use joint military exercises in Belarus as cover to invade from the north.
