The day before his impeachment trial is set to begin, Donald Trump's lawyers are urging the Senate reject the charges against him and are calling the hearings an "illegitimate partisan effort to take him down" by Democrats.Meanwhile, the prosecution team from the House has filed a stern reply to the president's legal team, following their response to a summons request calling the impeachment articles "constitutionally invalid." House managers replied, calling the president's assertion that he can't be removed from the presidency "chilling" and "dead wrong".
