McGhee was named to the team representing the US at the
William Jones Cup competition in
Taipei, Taiwan in July 1987. The team won all seven games to win the gold medal for the event. The USA was down at halftime in the opening game against Japan, but came back in the second half to win, helped by 15 points from Campbell. McGhee averaged 7.4 points per game over the seven games. McGhee was selected to be a member of the USA team invited to the
1994 World Championships. The preliminary rounds were held in
Hobart, Tasmania while the final rounds were in
Sydney, Australia. The USA team won their first six games before playing Brazil in the semi-final match up. Brazil's
Hortência Marcari had a great game scoring 32 points, and the final score of 110–107 favored the Brazilian team. The USA team regrouped to beat the host Australia team 100–95 to take home the bronze medal. McGhee averaged 5.3 points per game. McGhee was selected to represent the US at the
1995 Pan American Games. However, only four teams committed to participate in the women's basketball competition, so that event was cancelled. McGhee's final event as a member of the USA team was the
1996 Summer Olympics, held in
Atlanta, Georgia, USA. The USA team won all their pool play games by large margins, although they were behind Cuba by as much as seven points before
Lisa Leslie's 24 points, helped the USA take over the game. The USA victory over Australia featured a record setting 15 assists by Teresa Edwards, while Johnson was the leading scorer with 24 points. Against Japan, Lisa Leslie set a USA Olympic scoring record with 35 points. In the final, the USA team faced 7–0 Brazil—a team that had beaten the USA squad in the 1991 Pan Am games and the 1994 World Championships. This time, playing before a home crowd of 32,987, the USA team started out very strong, hitting 71.9 per cent of their field goals leading to an eleven points margin at the half. The USA team scored the first eight points of the second half and won the gold medal 111–87. McGhee averaged 3.1 points per game. ==Career statistics==
