U.S. Secretary of State Antony Blinken on Wednesday said the United States has not seen any pullback of Russian troops from Ukraine's borders.

White House spokeswoman Sarah Sanders disparaged Mueller's investigation as the "Russian Witch Hunt Hoax" in a statement and added "unfortunately, it probably does undermine our relationship with Russia."

The relationship between the United States and Russia is worse now than it ever was — including during Cold War, according to U.S. President Donald Trump.
