Gingrich formally ends tumultuous White House bid

Newt Gingrich ended his tumultuous run for U.S. president on Wednesday after dazzling in televised debates but winning only two of the dozens of nominating contests in the Republican primary race.

The former U.S. House of Representatives speaker, the face of the Republican party in the mid-1990s, badly trailed front-runner Mitt Romney in polls and his campaign fell into debt of $4.3 million. (Reuters)
