Tobacco companies have moved swiftly to strengthen their grip on Washington politics. Day one of Donald Trump's presidency started with tobacco donations, senior figures have been put in place within the Trump administration who have deep ties to tobacco, and lobbying activity has increased significantly. America's largest cigarette manufacturers, Reynolds American and Altria Group, donated $1.5m to help the new president celebrate his inauguration.

In the first quarter of 2017, tobacco companies and trade associations spent $4.7m lobbying federal officials. Altria, the company behind Marlboro, hired 17 lobbying firms. Reynolds, makers of the Camel brand, hired 13. Politicians and officials with deep ties to the tobacco industry now head the US health department, the top attorney's office and the Senate.

Trump himself ... has revealed that he had investments in tobacco companies, including Philip Morris International, its American spinoff Altria Group, and Reynolds American Inc..
