Donald Trump's first year: in pictures White House staffers - 25 July 2017

Former campaign manager Corey Lewandowski says hello to reporters as he and White House advisors including Communications Director Anthony Scaramucci accompany President Trump for an event celebrating veterans at AMVETS Post 44 in Ohio, July 25, 2017. Jonathan Ernst: "The most visible person in any White House is naturally the President, followed by the press secretary. But there are also the staff who support them. For those of us covering the Trump administration, there seem to be more compelling figures in the West Wing than ever before. It's crucial to know who's who and why they're important. When I raised my camera and back-pedalled ahead of the group to take this image Lewandowski gave me a hello. I liked the photo, but had no idea it would go a little bit viral, especially since Scaramucci, who was the biggest mover and shaker that week, was hidden back in the pack. But I guess the image catches a glimpse of what it's like to be a West Wing staffer on the road."
