Washington, Jan 29 (IANS): US President Trump has signed three more executive actions that focussed on lobbying ban, reorganization of the National Security Council (NSC) and a plan to defeat the Islamic State (IS).

Trump signed the actions on Saturday in the Oval Office surrounded by several of his aides and in front of reporters, CNN reported.

When signing his action calling for a five-year lobbying ban for administration officials, Trump referred to a ban imposed by his predecessor, former President Barack Obama.

Like Trump, Obama campaigned on a vision of Washington reform, promising to target the revolving door of political service and lobbying jobs.

Once in office, he ordered a two-year ban on administration officials from lobbying. Trump said on Saturday Obama's ban was insufficient.

"It's a two-year ban now, and it's full of loopholes," Trump said, before quipping to his staff, "You have one last chance to get out."

Administration officials also said Saturday's lobbying ban would include a lifetime prohibition on lobbying on behalf of foreign governments.

However, Trump's move to ban his aides from cashing in on their current jobs may be easier said than done.

Lobbying can be ambiguously titled in practice, and while former staffers may not become registered lobbyists, they could potentially trade influence and government experience for a hefty paycheck all the same.

The text of the NSC memorandum as provided by the White House established the organization of Trump's National Security Council, providing specific roles for his national security adviser Michael Flynn and homeland security adviser Tom Bossert.

The action on IS outlined specific requirements of the plan Trump wants, including a "comprehensive strategy," recommended changes to the rules of engagements and use of force as well as the "identification of new coalition partners."

The president called for a plan to be delivered to him within 30 days on how to defeat the IS.

The nation's top military advisers had been readying a plan for Trump, who met the Joint Chiefs and Secretary of Defense James Mattis at the Pentagon on Friday.

Mattis and Joint Chiefs of Staff Chairman Gen. Joseph Dunford have been reviewing potential options for dealing with the terrorist group, and the action signed Saturday calls for Mattis to coordinate with Dunford, the director of national intelligence and other Cabinet officials to shape the plan.

After signing the action on IS, Trump said, "I think it's going to be very successful."

"That's big stuff," he added.
