Johnson isn't the only Georgia congressman to travel to the West Bank over the last two years.
Three Republicans -- U.S. Reps. Buddy Carter, Barry Loudermilk, Rick Allen -- and their wives stopped in Ramallah last summer as part of a week-long trip to Israel that was underwritten by the American Israel Education Foundation, a charity closely affiliated with the pro-Israel lobby group AIPAC.
According to the nonpartisan LegiStorm, which collects data on privately funded lawmaker trips, the West Bank was the second most popular international destination for members of Congress and their staffs in 2015 and 2016, coming in behind Israel. Groups spent more than $1.6 million to send lawmakers and their staffers there.
