After the tech and social media mogul, 40, dined with the 78-year-old Republican at his Mar-a-Lago resort last month, he's now pledged his support by donating the huge sum towards the collection to cover the costs of Trump's swearing-in ceremony on January 20.

The pair have put the past behind them as they've not always seen eye to eye.

Meta's Facebook and Instagram suspended Trump's accounts on the apps in 2021, after he allegedly showed his support to the mob that stormed the U.S. Capitol in an attempt to overturn the 2020 presidential election results.

Trump - who previously held office at the White House between 2017 and 2021 - previously branded Facebook "an enemy of the people".

The former reality star is also close buddies with another tech mogul, Tesla and X (formerly Twitter) owner Elon Musk, 53, who he has made the head of his newly formed Department of Government Efficiency (DOGE) alongside Vivek Ramaswamy.

Zuckerberg and Musk have had a frosty relationship, which heightened after the latter acquired Twitter for $44 billion in 2022.
