Richard Schiff has told how he had to have a conversation with his wife about never seeing her again as he battled Covid-19.
The 65-year-old, best known for playing White House communications director Toby Ziegler in the political drama, was admitted to hospital in the US last month.
Speaking on Good Morning Britain, he said: "I'm an ex-smoker and I’m pre-diabetic and I’m old.
"I’m an old dude, and so I have some strikes against me, so I anticipated this was possible, but when it happened, it was really scary."
He added: "I had to have the conversation with my wife, about maybe not seeing her again and because the doctor had convinced me that it was going to be touch and go."
"The worst part of it is the epiphany, the realisation that you might never get to touch each other again and that for some reason struck me, struck home more than anything else."
'It was really scary.'
