House Republicans are finding it tough to get cooperation from their Senate colleagues in an effort to reduce government-subsidized lobbying by nonprofit groups.

As many as 100,000 groups received $39 billion in government grants last year, but they do not open their books to government inspection.

House Republicans want them to submit to outside audits and spend no more than 5% of their federal funds on lobbying.

Here are some examples of their government-funded activities:

• The National Council of Senior Citizens spent part of its $71 million in government moneys to erect a paper-mache Trojan Horse to protest GOP efforts to reduce the growth of Medicare.

• Part of the $22 million in grants received by the American Bar Association went to defend flag burning.

• The Child Welfare League used part of its $250,000 grant for an advertising campaign to increase welfare spending.

• Some of the $1 million each received by the AFL-CIO and the Teamsters went to oppose Medicare reforms.

• The American Association of Retired Persons, which gets $24 million, engages in partisan political campaigns to defeat politicians who oppose their agenda.
