Tickets for US President Donald Trump's first State of the Union address later on Tuesday have had to be urgently reprinted because of a glaring typo which lawmakers mocked.

The offending tickets invited people to attend Mr Trump's "State of the Uniom".

"Looking forward to... State of the Uniom," Sen Marco Rubio tweeted, while one social media user asked: "Will they be serving covfefe...?"

This was a reference to a tweet by Mr Trump in May, which left many puzzled.

It was an apparent typo, though the president only ever offered a teasingly cryptic tweet about it.

But this time US officials were quick to point out that the "Uniom" typo had nothing to do with Mr Trump.

In fact, the error was made by the Sergeant at Arms of the US House of Representatives, whose office oversaw the printing of the tickets.

"There was a misprint on the ticket," a spokesman for the office told AFP news agency.

"It was corrected immediately, and our office is redistributing the tickets."

It was not immediately clear how many tickets were affected.

Anyone looking at the flawed tickets and wondering whether the word "visitor" in "Visitor's Gallery" should not be plural instead may be relieved to know it is not a typo - that's just what they call it.
