Nelson Benton, an Emmy Award-winning reporter and correspondent for CBS News for 22 years, is joining Mutual Broadcasting System as its White House correspondent next Monday.

The anchor at WMAR-TV in Baltimore for two years until this past November, Benton says quite frankly that he was looking for a place to land when the Mutual offer was made. "I have always had a fondness for radio," he says. "It is faster and in many ways easier. When I started out there was damn little television."

Benton started his career in 1949 as an announcer at WIST in Charlotte, N.C. He worked for four other stations in North and South Carolina before joining CBS in June 1960, where he stayed until November 1982 and where he was part of a team that won an Emmy in 1973 for a program on the Watergate tapes.

At Mutual, Benton will also coanchor "Reporters' Roundup," a weekly interview show heard on WTOP-AM (1500) at 11:05 p.m. Saturdays.

Other appointments announced by Ron Nessen, vice president for news at Mutual, and effective Monday are: Bill Groody, executive editor of "Lifestyle Reports," which is carried on WINX-AM (1600); Peter Maer, U.S. Senate correspondent and coanchor of "Reporters' Roundup"; Dan Scanlan, U.S. House correspondent; Paul Henderson, morning drive anchor; Jim Bohannon, anchor of morning "Lifestyle Reports"; John Hartge, business reporter; and Ross Simpson, principal reporter for "America in the Morning."
