Former president Bill Clinton offered lukewarm support for Barack Obama through a spokesman today.
"President Clinton is obviously committed to doing whatever he can and is asked to do to ensure Senator Obama is the next president of the United States," Mr Clinton's spokesman Matt McKenna told Reuters in a one-sentence e-mail.
Two weeks after his wife ended her White House bid, Mr Clinton, who gave the Democratic presidential candidate's energy policy faint praise over the weekend, has not yet said in public that he would support Mr Obama.
On Sunday Mr Clinton made his first public address since his wife, Hillary, ended her presidential campaign on June 7th after her rival secured enough support to be the Democratic nominee in the November election.
The only time he mentioned Mr Obama during a speech to the US Conference of Mayors was when Clinton said he preferred the Democrats' energy policy to that of Republican rival John McCain.
The former first lady has endorsed Mr Obama, urged her supporters to rally behind him and is scheduled to campaign with him on Friday in Unity, New Hampshire.
But her husband, the last Democrat to be US president, ignored journalists on Sunday when asked when he might publicly endorse Mr Obama.
