How can I get the airy soft look of Melania Trump's official portrait? There was clearly a flash a bit to her left (photographer's right) as evidence by the darker left side (her right) and the reflection in her eyes. It looks fairly round - any idea if this is a continuous tungsten or a flash? What type of modifier or settings may have been used?

If you want to also explain some of the post processing that's cool too. But I'm more interested in the lighting.
