Police have arrested a man in the Moss Side area of Manchester in connection with Monday's attack.
Eight men remain in custody as part of the investigation, Greater Manchester Police say.
The Question Time debate turns to the leaking of details of the Manchester investigation - including photos from the scene - to the US media.
Amber Rudd says Theresa May has raised the matter with US President Donald Trump, and that she does not think the leaks have damaged the investigation.
The home secretary, who has previously expressed her irritation at the reports appearing in the US media, adds: "It must have been such a terrible thing for the families to see."
Labour's Greater Manchester Mayor Andy Burnham says what has happened is "absolutely outrageous".
"It's wrong, it's arrogant of the Americans and it's disrespectful to the people of Greater Manchester and most importantly the families of those who have died."

"I'm a proud Manc and a proud Muslim", says a man in the Question Time audience.
"What happened on Monday night was an evil act and abhorrent act," he says.
He warns that Muslims can be "collateral" damage after a terror attack if Islamophobia increases. Let's not be divided, he says.
The home secretary rejects criticism of cuts to police budgets, which some warn have affected on-the-ground intelligence about possible extremism.
"We must not imply that this terrorist activity would not have taken place if there were more police," she says, on Question Time.
Good counter-terrorism policy relies on strong relationships between the police and the intelligence services, she says: "It's not about those pure numbers on the street."
She adds: "It's not about policing, so much as engaging with community leaders in the area."
