"The interview ended abruptly, leading to speculation it had been cut short."

Is there a "that", which might be there after speculation, omitted?

 

[Raymott]

Yes

 

[lagoo]

Yes

Thanks.
But "that" can't be omitted in an appositive clause, or the given sentence is not an appositive clause?

"That" probably should not have been omitted in the above.

But "that" can't be omitted in an appositive clause, or is the given sentence [STRIKE]is[/STRIKE] not an appositive clause?

Please note the correct way to ask your question.

The sentence doesn't make any sense. If it ended abruptly, then it was cut short. No need to speculate.
