A defense lobbyist and his family made $1.5 million in political contributions from 2000 through 2008 as the lobbyist's now-embattled firm helped clients win billions of dollars in federal contracts. A sizable chunk of those campaign dollars went to the House members who control Pentagon spending.

Paul Magliocchetti, founder of the PMA Group, and nine of his relatives -- two children, his daughter-in-law, his current wife, his ex-wife and his ex-wife's parents, sister and brother-in-law -- poured contributions into the coffers of candidates, political action committees and national and state party committees, according to a CQ review of public documents.

During this time, PMA grew from a start-up to the 11th-richest lobbying outfit in the country.

The top beneficiaries were a select group of Democratic members of the Defense Appropriations Subcommittee, other allies of the top Pentagon appropriator in the House, Rep. John P. Murtha , D-Pa., and the company's own political action committee, which in turn made contributions to many of the same lawmakers.
