Two men have been charged over malicious communications which were sent to Ashton-under-Lyne and Failsworth MP Angela Rayner.
A 53-year-old man from Halifax has been accused of making malicious calls to the deputy leader of the Labour Party on 15 October.
A 71-year-old man from Sheffield has been charged over an email sent to Ms Rayner the following day.
They have both been bailed to appear at Westminster Magistrates Court on 17 March.
The men have both been charged with sending an offensive, indecent, obscene or menacing message.
A Labour spokesman said the party was working police to catch those responsible for the "abuse and threats" Ms Rayner had received.
