NEW Delhi's most vociferous critic on Capitol Hill, Republican Senator Dan Burton of Indiana, was the target of damaging allegations last fortnight—much to the delight of the Indian lobby. The charges: Burton had tried to shake down Mark Siegel, a former lobbyist to Pakistan, to the tune of $5,000, and consequently threatened him with loss of work if he did not raise funds for Burton's campaign. The disclosures, which had appeared in the Washington Post, carry extra ironic weight as Burton heads the highly-publicised House Reform and Oversight Committee probe into charges regarding illegal donations to the Democrats' coffers.
