GENEVA (AP) _ As Al Gore began his White House quest Wednesday in Tennessee, President Clinton chimed in from Europe with some campaign advice and a good luck message.

``The president believes that it's time for the vice president to get out and make the case, let the country know who he is, where he wants to take the country,'' White House press secretary Joe Lockhart said. ``He takes an important first step on that journey today.''

Lockhart, answering reporters' questions following Clinton's speech to the International Labor Organization, said the administration's economic, education and environmental policies ``will prove to be a very successful platform'' for Gore's candidacy.

Clinton wished Gore good luck during a telephone call from a limousine as the president headed to the Geneva airport and a flight to Paris.

Gore made his official announcement during a speech in his hometown of Carthage, Tenn.
