Inviting the wrong person to an event or a party is always embarrassing, but can be laughed off in hindsight.
However, a minor hiccup can't be so easily overlooked when it happens live on national TV.
That's what happened on Fox News on Monday when they amazingly managed to book the wrong Democratic senator to appear on Fox and Friends First.
They were under the belief that they had booked Ann Kirkpatrick, who is one of the only Democrats to have supported ICE and the Trump administrations' controversial handling of child immigrants.
You would think that tracking down someone like this wouldn't be that hard but, astonishingly, they booked Barbara L'Italien, a senator from Massachusetts who is currently running for Congress.
Sensing this as the perfect opportunity to criticise the president on a network that chooses to support him nearly every hour of the day, Barbara seized the moment and did not disappoint.
It takes a few moments for the presenters to actually realise what is happening as L'Italien goes on a full-blown rant against ICE and Trump, labelling their policy "illegal and inhumane".
The mother of four has since posted on Twitter about her appearance on Fox and admitted that she did this as she knew that Trump would be listening.
Desiree Dunne, the executive producer for Fox and Friends First, said in a statement given to The Washington Post that they had contacted Kirkpatrick's representative who had confirmed that she would appear on the segment.
This morning, we invited Congresswoman Ann Kirkpatrick to appear on ‘Fox & Friends First’ through her press contact on file, Joe Katz, who accepted the invitation on Kirkpatrick’s behalf.
Katz followed with an email confirming the segment, which also included background information and a campaign logo for Ann Kirkpatrick. During the actual segment, Barbara L’Italien, appeared on camera instead of Kirkpatrick.
Despite speaking to producers prior to the interview, L’Italien did not identify herself as anything other than Kirkpatrick until she was live on air, at which point we ended the interview.
L'Italien has since tweeted a version of the full statement that she had intended to read on Fox.
I refuse to believe that our only options are open borders or traumatizing children, and shame on you for pretending that they are.
Shame on you for putting this vile, racist policy in place.
Our immigration system should be just, fair, compassionate and reflect our values as a nation of immigrants. What we have now, what you are doing, is none of those things.
You are just being cruel to people who believed us when we said that this country was a land of freedom and opportunity.
You need to stop blaming everyone else for your moral failures and put a stop to this, Mr. President.
