US President Barack Obama has said he plans to take executive actions to reform the immigration system "by the end of the summer".

He said Americans could no longer wait for Republicans in the House of Representatives to take action.

He has asked the Secretary of Homeland Security Jeh Johnson and the Attorney General Eric Holder to examine what options are open to him to fix whatever elements he can.

He has charged them to report back to him "by the end of the summer" and said he would then adopt these intitiatives "without further delay".

He has also instructed them to move as many resources as possible from the interior of the country to deal with the humanitarian crisis currently happening on US borders.

Mr Obama said he had held off pressuring Republicans in the House for a long time, but then the Speaker of the House John Boehner had told him last week that he would be bringing an immigration reform bill for at least the rest of this year.

Mr Obama said this made "no sense" and was "just politics".  He scolded House Republicans for not taking action just because they were "mad" at him for "using Executive Actions too broadly".

He said he didn't enjoy taking Executive Action and that he would prefer a broader fix.

But he said the failure of House Republicans to pass "this darn bill" was bad for the US economy, security and future.

He said he was going to "fix as much as I can on my own".
