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

"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?

[teechar]

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

[Piscean]

I would use 'that', but the version without seems OK to me.

Please note the correct way to ask your question.

[SoothingDave]

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

[Piscean]

I think meetings can end abruptly without necessarily being cut short.
