First, Abramoff gave Bush/Cheney the money.
"According to an Oct. 15, 2003, story in Roll Call, Abramoff was one of a half-dozen lobbyists who raised $100,000 for Bush's 2000 campaign."
Then they set him up on the transition team.
"After the 2000 election, Abramoff was named to the Bush transition team for the Interior Department, which regulates the Indian casinos that paid Abramoff his inflated fees."
Then, they let him sit in on WH staff meetings.
"President Bush's Press Secretary Scott McClellan has now acknowledged that convicted GOP lobbyist Jack Abramoff attended staff meetings at the White House."
