The American President (1995) plot summary
The widowed President of the USA invites a woman he likes (Sydney) to a state banquet. They fall in love, but the press turns it into scandal and the opposition leader uses it as an excuse to run down the presidents character. He will not defend his private life to the world and his popularity at the polls plummets. He then loses the love of Sydney when he is forced to get the environment bill that she is campaigning for thrown out (and her fired as a by-product) to defend his own crime bill.
