Quesada accused Trump of lying to American taxpayers about fronting the bill

Former Mexican President Vicente Fox Quesada took to Twitter to make it clear that Mexico will not be paying for Donald Trump's controversial wall.

Quesada blasted The Donald tweeting: 'TRUMP, when will you understand that I am not paying for that f***en wall. Be clear with US tax payers. They will pay for it.'

He said earlier: 'Trump may ask whoever he wants, but still neither myself nor Mexico are going to pay for his racist monument. Another promise he can't keep.'

Quesada and Trump have previously sparred on the topic of the wall which was Trump's most famous campaign promise.

Quesada has consistently said Mexico will not pay for the wall.

During a campaign rally in February, Trump responded to this statement by saying the wall 'just got 10 feet taller'.

Beyond just the wall, Quesada also voiced his other qualms about Trump via Twitter.

'Sr Trump, the intelligence report is devastating. Losing election by more than 3M votes and in addition this. Are you a legitimate president?,' he tweeted Friday.

In addition to the wall, Fox also criticized the legitimacy of Trump's election win on Twitter

Current Mexican President Enrique Peña Nieto has also maintained the wall will not be funded by Mexico.

In an interview with CNN he said: 'There is no way that Mexico can pay [for] a wall like that.'

On Trump's campaign website, in a 664 word plan, it states Mexico will pay for the wall or the US will block wire transfers to Mexico. The site also states there would be higher visa fees as a cash source.

Friday, congressional Republicans started plans for building the wall along the southern border before Mexico has agreed to pay.

It could be funded as soon as April through the appropriations process. Trump has stated this will not cost the US taxpayers.
