Medications might also cause a drop in blood pressure. Beta-blockers and nitroglycerin, used to treat heart disease, are common culprits. Diuretics, tricyclic antidepressants, and erectile dysfunction drugs can also cause hypotension. Some people have low blood pressure for unknown reasons.
Theoretically, then, the President can probably pardon him/her-self for any Federal crime â but this only prevents actual prosecution for that crime, not impeachment for the crime itself. Prior Answer, to the hypothetical of the VP murdering the President and then pardoning himself:
Presidential pardon power derives from a specific grant in the Constitution. Article II, Section 2 vests the president with the âPower to grant Reprieves and Pardons for Offenses against the United States, except in Cases of Impeachment.â The Presidentâs pardon power is limited to federal offenses, which include federal prosecutions in U.S. territories like the District of Columbia and Puerto Rico.
