CNN aired a report explaining how through Obama's line of succession, which is in place until Trump takes the oath to be President, an Obama appointee would be the next President should Donald Trump be killed during the inauguration ceremony. The problem is, the report is inaccurate, contradicting the 20th Amendment of the United States Constitution.
It says in 20th Amendment: "If, at the time fixed for the beginning of the term of the President, the President elect shall have died, the Vice President elect shall become President." It goes on to say that if the choice devolves to the House of Representatives, it would be the job of the House of Representatives to choose the next President. At no point does the Constitution give the choice to a line of succession that is on its way out.
