Fidelity Investments has enlisted Hill & Knowlton as its lobbyist dealing with Securities and Exchange Commission regulations.

Legendary Frank Mankiewicz, H&K's 81-year-old vice chairman who headed National Public Radio and served as Press Secretaries to Sen. George McGovern and Sen. Robert Kennedy, and chief lobbyist Gary Hymel manage the account.

Fidelity, which has $2.2T in assets, has been under investigation by the SEC in a probe concerning gifts and gratuities.

Tom Eidson, Fidelity's executive VP and director of corporate affairs, had headed H&K until '96 when he took a leave of absence to write "All God's Children," a novel about a plucky Quaker widow who raises four sons on the Kansas prairie during the 1890s.
