US presidential election loser Hillary Clinton is to set up a Political Action Committee (PAC) to help organisations close to the her heart, it has been revealed.

According to Axios, the former first lady will launch the PAC as a way of "acting as a quiet catalyst" for organisations she cares about.

The aim is for it to eventually help 2018 congressional candidates, but with no intention of making it a vehicle to run for anything herself.

It has been rumoured that Clinton would run for New York Mayor, but all such claims have been quashed by the Clinton team.

According to a source familiar with the planning, the initial focus will be on lifting up organisations that are the product of the energy and activism she has seen since the election.

Since Donald Trump's election victory in November 2016, several large-scale protests have taken place in support of democracy, science and women's rights.

It has been reported that the former secretary of state has met with some of these groups, and it is something she's become increasingly passionate about with each meeting.

Clinton isn't aiming to use the PAC as a platform to comment on Trump's policies but said she won't shy away from expressing her views either.

Clinton is also writing a book to be released in the autumn. It will be based upon pieces of advice she has received throughout her career that have sustained her in hard times, including the last campaign. She is also set to return to giving paid speeches.

On Tuesday, Clinton pointed to the FBI letter from James Comey and Russian interference as reasons for her loss to Trump.

What is a PAC?

A PAC is a Political Action Committee which aims to raise money from members and donations to help fund political campaigns.

A Super PAC is a similar committee but can raised unlimited amounts of money but cannot be used to directly fund a candidate or party but can run alongside. Many of these helped to promote the likes of Clinton and Trump in 2016.
