Attorney George Conway, the husband of White House counselor Kellyanne Conway, has slammed President Donald Trump again, this time saying he's using a 'misleading' argument in his attack on the Ninth Circuit Court of Appeals.

Conway dove into statistics of Supreme Court reversals to counter a claim by Trump that the Ninth Circuit 'is overturned more than any Circuit in the Country.'

'The number of Ninth Circuit cases reviewed and reversed was high, but the Ninth Circuit is by far largest federal circuit by number of judges and size of docket,' Conway wrote on Twitter on Thursday.

'Anyway, to put the point more simply, the Supreme Court doesn't usually take cases to affirm them, which is why the statistic the President is citing is misleading,' he added.

He also pointed out that an average of 74 percent of all court rulings across the U.S. that were reviewed by the Supreme Court were overturned last year.

Trump has had the Ninth Circuit in his sights after it ruled against him in his attempt to stop illegal immigrants applying for asylum once they cross the border.

It also led to the president getting into an unprecedented battle with Supreme Court Chief Justice John Roberts.

The Ninth Court is the largest of the 13 circuit courts in the United States and its reversal rate in cases that go the Supreme Court is the third highest among all the appeals courts, coming in after the Sixth Circuit based in Ohio and the 11th Circuit in Atlanta.

Conway has become something of a social media star in his critical tweets on his wife's boss.

But he's caused a fury this month, when he co-wrote an op-ed in the New York Times that Trump's appointment of Matthew Whitaker as acting attorney general was unconstitutional.

He also gave an interview to the 'Skullduggery' podcast on Yahoo! News, where he said the Republican Party under Trump has become a 'personality cult' and that he would rather 'move to Australia' than vote for the president again.

But it was his comments on Whitaker that got the president's attention.

Trump said that 'Mr. Kellyanne Conway' was 'just trying to get publicity for himself.'

Kellyanne Conway, meanwhile, has brushed aside political differences with her husband.

'It doesn't affect me or my job at all,' she said on 'Fox News Sunday' recently.

'I've never been doing better personally or professionally,' she noted, adding: 'I'm sure the feminists are really cheering me on today, an independent, strong-willed, strong woman in a very powerful position that disagrees with her husband.'

Trump has been on a tear about the Ninth Circuit all week, even slamming it on Thanksgiving Day in a talk with reporters.

'Essentially they're legislating,' he said of the court which put a hold on his asylum ban on illegal immigrants.

'We are doing really well considering the laws are a disaster. And if we had the right laws, it would be a lot less expensive and we would do it a lot easier, but we don't have the right laws and we have people interpreting the laws and they always give us a bad interpretation. So hopefully we have shown some light on the Ninth Circuit,' he said.

Trump also acknowledged his spat with Supreme Court Chief Justice John Roberts.

'I know that Chief Justice Roberts, John Roberts, has been speaking a little bit about it. And I think - I have a lot of respect for him. I like him and respect him, but I think we have to use some common sense. It's Ninth Circuit, everybody knows it, it's totally out of control. What they're doing, what they're saying, the opinions are very unfair to law enforcement. They're very unfair to our military. And they're very unfair, most importantly, to the people of our country,' he said.

Trump had complained that a judge appointed by former President Barack Obama has ruled against his asylum ban, calling him an 'Obama-judge.'

That earned a sharp rebuke from the chief justice.

Roberts, who is a Republican and was nominated to the Supreme Court by George W. Bush in 2005, said: 'We do not have Obama judges or Trump judges, Bush judges or Clinton judges.

'What we have is an extraordinary group of dedicated judges doing their level best to do equal right to those appearing before them.

'The independent judiciary is something we should all be thankful for.'

Trump hit back on Twitter afterwards, saying: 'Sorry Chief Justice John Roberts, but you do indeed have 'Obama judges', and they have a much different point of view than the people who are charged with the safety of our country.'
