Former president George W Bush has turned his hand to pizza delivery to help staff left unpaid by a government shutdown.

Posts on social media showed Bush bringing the food to his Secret Service detail.

“It’s time for leaders on both sides to put politics aside, come together, and end this shutdown,” Bush wrote on Instagram.

The shutdown has entered a fifth week and is the longest in US history.

About 800,000 US federal staff are at home or working without pay during the political deadlock over funding for Trump’s proposed border wall.

This includes about 6,000 Secret Service staff, around 85% of whom are reportedly still working through the shutdown.
