Donald Trump became the third-ever president of the United States to be impeached by the House of Representatives. He was formally charged with abuse (滥用) of power on Dec 18, 2019. Nancy Pelosi, the Speaker of the House, said Trump used his powers as president for personal gain. A trial this month will decide whether he will be removed from office. However, in the 244-year history of the US, no president has yet been removed from office by impeachment.
