Presidential hopeful Donald Trump is facing yet another challenge in the person of Reid Hoffman who recently took to social media and challenge Trump to open his tax returns in exchange for $5 million.

The challenge came after Hoffman published a post on Medium putting the spotlight on Marine Corps veteran Pete Kiernan's crowdfunding campaign on CrowdPac. The original goal of the campaign was $25,000 and comes with a challenge to Trump. 

"Trump claims to love veterans, and so we're asking him to put his money where his mouth is," Kiernan wrote. He added that if Trump releases his tax returns, he will donate the money he raised to non-profit organizations that cater to veterans. 

Hoffman upped the ante and joined Kiernan in challenging the GOP presidential bet saying that if Kiernan's campaign reached its goal, he will double the amount, even willing to give $5 million if Trump takes the challenge.

He started his challenge by reminding Trump how he challenged President Obama, who was a candidate at that time, to release his passport applications and university records for $5 million. 

Hoffman's post bolstered the campaign's popularity and has already reached $43,000 on Monday. Before Hoffman's post, the campaign only raised around $5,000. This show of public interest bolstered Kiernan's confidence and modified the campaign's goal to $1 million. 

Despite his challenge to Trump, Hoffman hasn't revealed to anyone which presidential candidate he is supporting. For Democrats, however, this gives Hillary Clinton a much needed upper hand considering the blow she took after her "overheating" incident during the 9/11 ceremony. 

With both men challenging Trump, all eyes are now on the GOP candidate waiting what his move will be in response to that challenge. It can be remembered that a similar challenge has been given to Gerald Ford in the 1976 elections where he lost to Jimmy Carter after failing to disclose his financial records. Will Trump follow Ford's steps and fate or he will have a different one remains to be seen?
