The fact (as opposed to 'alternative fact') that Trump is British slang for Fart has been widely shared on social media, so it isn't news.
If this was news, then the Orange One would probably hold a press conference to deny it or have the White House 'Groom of the Stool', a snivelling, odious wretch called Sean Spicer, do it for him. The weird thing is that some of the audience would applaud, as they tend to do whatever rubbish he comes out with. This, according to the many sources (including the Huffington Post) is because Trump actually hires people to applaud on these occasions.
There's a word for these professional sycophants - such a group is called a claque and it follows that a member of that group is a claquer - or if you prefer to Anglicise, a 'clacker'.
Now, in a delightful example of serendipity, 'Clacker' happens to be Australian slang for Arsehole.
Where else would you expect to find the most powerful fart in the world than in the presence of a number of professional arseholes?
