Barack Obama stated: "From constructing our Kitchen Garden to brewing our own Honey Brown Ale, Sam has left an indelible mark on the White House. And with the work he has done to inspire families and children across this country to lead healthier lives, Sam has made a real difference for our next generation. Over the years, Sam has grown from a close friend to a critical member of my team, and I am grateful for his outstanding work and look forward to seeing all that he will continue to achieve in the years ahead."Michelle Obama said: "Sam has been an integral part of Let's Move! from its very beginning -- from discussions about children's health around my kitchen table in Chicago, to setting the strategic vision of a national campaign in the White House, to spearheading efforts with the private sector across the country. Sam leaves an extraordinary legacy of progress, including healthier food options in grocery store aisles, more nutritious school lunches, and new efforts that have improved how healthy food is marketed to our kids.
