President Donald Trump says former national security adviser John Bolton was not aligned with his administration’s priorities.

Speaking to reporters Wednesday in the Oval Office, Trump says Bolton wasn’t getting along with other members of his administration. Trump is also critical of Bolton comparing the effort to denuclearize North Korea to the “Libya model,” words which angered Kim Jong Un ahead of their sit-down last year.

Bolton left the administration Tuesday after clashing with Trump on his efforts to hold negotiations with the Taliban and Iranian President Hassan Rouhani. Trump says he asked Bolton to resign, but Bolton claims he did so on his own accord.

Trump also tells reporters he disagreed with his former aide on Venezuela policy.

President Donald Trump also says his administration will propose banning thousands of flavors used in e-cigarettes amid an outbreak of breathing problems tied to vaping.

State and federal health authorities are investigating hundreds of breathing illnesses reported in people who have used e-cigarettes and other vaping devices.

No single device, ingredient or additive has been identified.
