I’ve been curating the BBC feed, choosing not to add much of the “analysis” portions, but this one adds a bit to our understanding …

Ivanka Trump, through her demeanour, is trying hard to look like a cooperative witness.

She’s smiling brightly, being courteous to the judge and court staff, and answering questions in an even tone.

At one point early in questioning, she joked that she couldn’t remember a call because it happened when she was nine months pregnant with her first child - more than 12 years ago.

But for such a high-ranking executive, her sudden amnesia on the stand is coming off as a calculated attempt to not give prosecutors any more ammunition.

Even when she’s presented with evidence, she says it doesn’t refresh her memory.

This is visibly frustrating prosecutors.
