You are very special,” before signing off.In a series of tweets Wednesday evening, Secretary of State Mike Pompeo called the storming of the U.S. Capitol “unacceptable.””Lawlessness and rioting — here or around the world — is always unacceptable,” the nation’s top diplomat wrote.”Let us swiftly bring justice to the criminals who engaged in this rioting,” Pompeo wrote, adding “America is better than what we saw today.”The scenes of crowds storming into the U.S. Capitol shocked foreign powers around the world.An explosion caused by a police munition is seen while supporters of U.S. President Donald Trump gather in front of the U.S. Capitol Building in Washington, U.S., January 6, 2021.Leah Millis | ReutesPrime Minister of the United Kingdom Boris Johnson described the unfolding protest in Washington as “disgraceful.””The United States stands for democracy around the world and it is now vital that there should be a peaceful and orderly transfer of power,” Johnson wrote in a tweet.Canadian Prime Minister Justin Trudeau also expressed concern about the violent scenes and said he was following the situation “minute by minute.””I think the American democratic institutions are strong, and hopefully everything will return to normal shortly,” Trudeau told the News 1130 Vancouver radio station.In a recorded statement, French President Emmanuel Macron said “what happened today in Washington, D.C., is not America, definitely.” “We believe in the strength of American democracy,” he added.”The violent acts against American institutions are a grave attack against democracy,” wrote Jean-Yves Le Drian, France’s Minister for Europe and Foreign Affairs.”The American people’s will and vote must be respected,” he added.Spanish Prime Minister Pedro Sánchez wrote that he was following the updates from Washington and that he was hopeful a Biden administration would be able to unite Americans.David-Maria Sassoli, the president of the European Parliament, the lawmaking party of the European Union, wrote that the scenes from the U.S. Capitol were “deeply concerning.””Democratic votes must be respected.
