“Today, I’m pleased to announce a new book and exhibit at @thebushcenter honoring new Americans who have contributed to the cultural richness, economic vitality, entrepreneurial spirit, and renewed patriotism of our country. As I said from the Oval Office in 2006, ‘America can be a lawful society and a welcoming society at the same time’,” Bush wrote in an Instagram post.

They are four-color paintings of immigrants he has come to know over the years, along with biographical essays he wrote about each of them.
