US President Donald Trump took to Twitter on Sunday (23 July) to furiously criticise Republicans saying they "do very little to protect their president." Following a day at the Trump National Golf Club in Potomac Falls, Virginia, Trump wrote: "It's very sad that Republicans, even some that were carried over the line on my back, do very little to protect their President."

It is unclear which members of the Republican party he was referring to.

His tweet came after another post in which he dismissed the ongoing federal investigation into Russian meddling in the 2016 presidential election and possible ties between Trump's team and Moscow as a "witch hunt."

"As the phony Russian Witch Hunt continues, two groups are laughing at this excuse for a lost election taking hold, Democrats and Russians!"

Members of the Republican party are involved in the various probes of Trump's interactions with Russia during the election season.

In his most recent tweets, the president also called on Senate Republicans to advance promised legislation to overhaul former President Barack Obama's healthcare law. Last week, Republican efforts to repeal and replace the Affordable Care Act, also known as Obamacare, failed in the Senate after several GOP senators said they would oppose the bill.

Twitter swiftly slammed the president's latest tweets lambasting members of his own political party, describing them as the "rantings of a spoiled child."

Many pointed out that the United States Congress was established as a separate structure from the executive and judicial branches of government to represent and protect the interests of the American people.

"It's their job to protect us...you foolish little goon!" Days of Our Lives actor Billy Flynn tweeted.

Comedian Larry Murphy wrote: "You've never in your privileged and entitled life carried anything on your back metaphorically or otherwise. Low energy. Weak."

One Twitter user wrote: "That should make you think. If in fact they owe you that much politically and still won't defend you, then the problem is probably you."
