President Donald Trump's cheeky bite back to a Senate Republican at odds with his 'big, beautiful bill 'made waves across social media platforms Thursday morning.

Kentucky Republican Rand Paul had previously told reporters Wednesday that the White House had disinvited him from the annual Congressional Picnic, set to take place there later Thursday evening.

But Trump contradicted his own White House on Thursday, indicating that 'of course' Paul and his family could attend. 

'He's the toughest vote in the history of the U.S. Senate, but why wouldn't he be? Besides, it gives me more time to get his Vote on the Great, Big, Beautiful Bill,' Trump wrote in a post on his social media site Truth Social on Thursday morning.

'It will help to, MAKE AMERICA GREAT AGAIN! I look forward to seeing Rand. The Party will be Great!' Trump concluded.

Speaking to reporters out side of the Capitol Wednesday, Senator Rand Paul (R-Kentucky) shared that his invitation to the President's Congressional picnic had been cancelled.

'I've just been told that I've been uninvited from the [White House] picnic...every Democrat will be invited, every Republican invited, but I will be the only one disallowed. I just find this incredibly petty', Paul said.

The Daily Mail is reaching out to Paul's office to see if the senator is choosing to take up the president's new invitation. 

President Trump has had Paul in his crosshairs over the past few weeks, as the Senator has been opposing the president's 'big,beautiful' budget bill.

Paul's primary opposition to the legislation has been over the projected new additions to the national debt.

While he wants to see the President's 2017 tax cuts extended, Paul has portrayed the current $5 trillion in new debt as 'Biden spending levels.'

'This will be the largest increase in the debt ceiling ever in our history. We've never raised the debt ceiling without meeting the target,' Paul told Fox News earlier this month. 'I think it is a terrible idea to do this' Paul told Fox News earlier in June.'

During another recent appearance on CBS' Face the Nation, Paul told host Margaret Brennan that the math in Trump's 'big beautiful bill' 'doesn't really add up.'

'One of the things this big and beautiful bill is, is it's a vehicle for increasing spending for the military and for the border. It's about $320 billion in new spending,' Paul said at the time.

  Trump has been attacking Paul on social media for weeks just as Senate Republicans have been grappling with the massive spending legislation.  

'Rand Paul has very little understanding of the BBB, especially the tremendous GROWTH that is coming. He loves voting 'NO' on everything, he thinks it's good politics, but it's not. The BBB is a big WINNER!!!' Trump wrote on Truth Social.

White House Press Secretary Karoline Leavitt has also piled on.

'Well, anyone who votes against the one big, beautiful bill including Senator Rand Paul, will be voting for a tax hike of more than $4 trillion on the American people and their voters will know about it,' Leavitt warned earlier this month.

Paul was first elected to the U.S. Senate in 2010, long before Trump's foray into politics, and was easily reelected to a third term in 2022 during Joe Biden's presidency. Paul is not up for election again until 2028.

Kentucky's other Senate seat is up as an open seat in the 2026 midterms election.

The commonwealth's senior senator and former Senate leader Mitch McConnell - another running Trump nemesis -- is not running for another term.
