Actor George Clooney because he was a "lifelong liberal Democrat" and director Judd Apatow because he "believes Trump does not have the intellectual capacity to run as President".

The tracker was put together by contractor Atlas Research, which was paid US$15 million by the administration and includes notes on some 274 US celebrities.
Documents for the US$25m taxpayer-funded project were obtained by Democratic House politicians, according to The Washington Post.
In a letter sent to the US Secretary of Health and Human Services (HHS) Alex Azar, three high-ranking democrats wrote that the HHS Assistant Secretary Michael Caputo was trying to use the project to boost Trump's popularity.
One document they obtained from a contractor showed Caputo suggesting the theme "Helping the President will Help the Country".
The Washington Post claims some celebrities had been excluded from the Public Service Announcements for publicly supporting former president Barack Obama, or for criticising Trump, or being supportive of same sex marriage, or gay rights.
None of the public service announcements have yet been put to air.
Caputo, who announced he was taking 60 days of leave in September, has not commented on the allegations in The Washington Post's report.
