Violent protestors last month occupied three cabinet ministry buildings as they sought to overthrow the Ukrainian government. Protestors physically blocked the speaker of the Ukrainian parliament from taking his seat at the speaker's podium for weeks. Then they blockaded the speaker of parliament in his own office, forcing him to escape out the window.
As the Ukrainian authorities attempted to restore order and evict protestors from government buildings, the US government threatened sanctions and more if the legally-elected government of Ukraine moved against those occupying government buildings.
Senator John McCain last week threatened unspecified "concrete" US action against Ukraine if there is any "brutal repression of the demonstrations." In other words, if police forcibly remove those who have taken control of cabinet ministry buildings and blocked the main square of the capitol, McCain implies that "all options are on the table."
Meanwhile in Washington:
A man attempted to climb the fence surrounding the White House today and was immediately apprehended. The White House complex was placed in full lockdown mode. According to press reports, "the area around the White House was shut down and reporters were not allowed to leave through one of the gates because of the incident."
Last October, a distraught woman traveling with her one year old daughter bumped into a barricade in front of the White House before driving quickly and erratically toward Capitol Hill. She did not attempt to occupy any government buildings, but once she stopped her car, police shot her dead.
