AP's take on who could still be ensnared by prosecutors in the Abramoff case -- Tom DeLay, John Doolittle, Conrad Burns and Steven Griles:

The investigation had already ensnared Ney's former chief of staff as well as two aides to former House Majority Leader Tom DeLay, R-Texas. The investigation cost DeLay his leadership seat before he ultimately resigned, and it contributed to the Election Day defeat of Sen. Conrad Burns, R-Mont.

Safavian was sentenced in October to 18 months in prison for lying to investigators about his ties to Abramoff. He is asking a federal judge to postpone his sentence until he can appeal his conviction.

Burns, who received about $150,000 in Abramoff-related donations and whose aides traveled on the lobbyist's jet to the 2001 Super Bowl, has denied any wrongdoing. Though two of DeLay's aides have pleaded guilty, the former majority leader maintains his innocence and has not been charged.

Also under scrutiny are Rep. John Doolittle, R-Calif., who accepted campaign money from Abramoff and used the lobbyist's luxury sports box for a fundraiser without initially reporting it, and former Deputy Interior Secretary Steven Griles, who senators and a former colleague said gave preferential treatment to Abramoff and his Indian tribe clients.
