as “political theater” by Democrats.

Democrats have put climate change back on the agenda in Congress after re-gaining the majority in the House earlier this year, holding dozens of hearings on the issue.

Many of the Democratic candidates hoping to challenge Trump in the 2020 presidential election have made climate change a top-tier issue of their campaigns. All have backed re-entering the United States into the Paris Climate Agreement.

A few candidates, including most recently former Texas Representative Beto O’Rourke, have also supported setting a goal for the United States to reach net-zero emissions by 2050 - one of the goals of the Paris agreement.The man responsible for the Westminster attack was 52-year-old Khalid Masood.

He was born as Adrian Russell Elms at Hainault Maternity Hospital, Erith, south-east London, on Christmas Day in 1964.

His father played no part in the newborn's life - and when his mother Janet married two years later, the boy was given his step-father's surname, Ajao.

The future killer would use the surnames interchangeably as an adult, before he converted to Islam and became Masood.
