In 2011, Le Pen took over leadership of the party founded in 1972 by her father, Jean-Marie Le Pen. U.S. President Donald Trump told The Associated Press on Friday he thought the attack will “probably help” Le Pen because she is the candidate who is “strongest on borders, and she’s the strongest on what’s been going on in France.”

Trump told the AP in an interview he was not explicitly endorsing Le Pen but that he believes the attack will affect how French people vote on Sunday.
The first polls since April 20's attack indicate a slight bump for Marine Le Pen over Jean-Luc Mélenchon and François Fillon, though they still show her losing to Emmanuel Macron in the first and second rounds of the election.
