French senators say they think French President Emmanuel Macron's security has been affected by the conduct and actions of an ex-aide at the center of a political scandal.

A Senate commission released a report Wednesday about the former security aide, Alexandre Benalla. He was fired in August after a video surfaced of him beating a protester at a May Day demonstrator last year.

Philippe Bas, president of the Senate Laws Commission, said the panel found elements showing "there have been numerous errors, irregularities and missteps" before and after Benalla was fired from the presidential Elysee Palace.

Paris prosecutors opened an investigation last week of whether Benalla told lies during the investigation.

Benalla was jailed on Tuesday night for allegedly not respecting the conditions of his judicial supervision.
