Joe’s brother James Biden has been an integral part of the family political machine from the earliest days when he served as finance chair of Joe’s 1972 Senate campaign.
In fact, since Joe joined the Senate, James has accompanied him on congressional delegation trips overseas. 
As vice-president, Joe brought James to White House functions. 
Sometimes, James’ White House visits dovetailed with his overseas business dealings, and his commercial opportunities flourished during his brother’s tenure as vice president. 
James was named executive vice president of HillStone International (a subsidiary of the huge construction management firm, Hill International) less than three weeks after the president of the company, Kevin Justice, visited the White House in 2010. 
James had virtually no experience with housing construction, but following his being given that position, HillStone international started getting huge government contracts.
James Biden joined HillStone just as the firm was starting negotiations to win a massive contract in Iraq. 
Six months later, the firm announced a contract to build 100,000 homes as part of a $35 billion, 500,000-unit project deal with TRAC Development, a South Korean company. 
HillStone also received a $22 million U.S. federal government contract to manage a construction project for the State Department.
It was the most lucrative contract the firm ever acquired.
