So now it's official. 

The US House of Representatives has passed two articles of impeachment against President Donald Trump.

The result from the Democrat-controlled House was no surprise.

In fact, we've been expecting this outcome ever since Democrats announced an impeachment inquiry back in September.

There is a similar sense of expectation ahead of next month's trial in the Republican-controlled Senate where Donald Trump is expected to be cleared.

But while it's highly unlikely that he'll be removed from office, the impeachment process is damaging for the US President.

Mr Trump has now officially joined a very unique club and earned a special place in the history books becoming only the third US president ever to be impeached.

This will be a stain on his legacy.

Mr Trump knows this and isn't happy about it.

We saw evidence of this in the furious six-page letter he sent to the Speaker of the House Nancy Pelosi ahead of the impeachment vote

That anger was also on show at a rally in Michigan last night in the appropriately-named town of Battle Creek where Mr Trump was certainly in the mood for a fight.

Addressing supporters as the impeachment vote was taking place on Capitol Hill, he described Ms Pelosi as crazy and said it was Democrats who should be impeached and not him.

It is a taste of what's to come. 

We can probably expect lots of references to the unfair, witch-hunt impeachment at Mr Trump's rallies throughout next year's election campaign.

The whole process doesn't seem to have damaged his approval ratings and the country remains split over whether or not he should be removed from office. 

Impeachment may even benefit the US president politically and help him to secure reelection.

That would be the ultimate vindication for Mr Trump.

But he is now an impeached president and that cannot be undone.
