Just days after he announced plans to recontest his seat at the next federal election on the basis that he still had much to contribute to his electorate -- particularly around transport issues -- former prime minister Tony Abbott is in the United States this week to give a speech to the Alliance Defending Freedom (ADF), an ultra-conservative religious organisation in the US opposed to same-sex marriage and abortion rights.

Fairfax reported Abbott's speech would be on "the importance of the family", but it is unclear whether the speech will be released, and the ADF is reportedly declining to tell journalists precisely when and where the speech will take place.
