President Trump's promise to make permanent cuts to payroll taxes if re-elected will deplete the Social Security and Medicare trust funds they finance, Senate Minority Leader Chuck Schumer (D-N.Y.) said Sunday on ABC's "This Week".

Driving the news: President Trump Saturday signed an executive order deferring payroll taxes for Americans earning less than $100,000 a year, and floated eliminating the tax altogether for those Americans if he is re-elected. It's unclear if Trump has the authority to suspend payroll taxes by executive action.

White House trade adviser Peter Navarro defended President Trump on Sunday for spending the weekend at his golf club in New Jersey and signing executive orders in the absence of a congressional deal on coronavirus aid, calling him the "hardest-working president in history."

Why it matters: Trump has received bipartisan pushback and allegations of executive overreach for the orders, which include an extension of extra unemployment benefits. Democratic leaders have called for Republicans to return to the table and compromise, but there remains a trillion-dollar gap in the size of the package that each side is seeking.

House Speaker Nancy Pelosi claimed on "Fox News Sunday" that states don't have the funds to comply with the executive order President Trump signed on Saturday, which requires them to cover 25% of an additional $400 in weekly unemployment benefits.

Why it matters: Many state and local governments have had their budgets devastated by the economic impacts of the coronavirus, which have caused expenses to soar and revenues to plunge.

White House economic adviser Larry Kudlow said on CNN's "State of the Union" Sunday that he regrets suggesting this week that unemployment benefits can only be extended by Congress.

Why it matters: President Trump's decision to bypass Congress to sign four executive actions, including one that provides $400 per week in extra unemployment benefits, has prompted outcry from Democrats and even some Republicans who believe he is overstepping his constitutional authority.

President Trump, speaking from a podium at his golf club in Bedminster, N.J., on Friday announced that he is prepared to issue executive orders suspending payroll taxes and extending enhanced unemployment benefits through the end of 2020, and halting student loan interest and payments indefinitely.

Why it matters: The impending orders come after talks between the White House and Democratic leadership collapsed Friday afternoon. But Trump said he remains committed to striking a deal with Congress on a broader stimulus package before signing the orders.

President Trump tweeted on Friday that his administration is "going a different way" with coronavirus aid after negotiations with congressional Democrats stalled again, suggesting he will use an executive order to address stimulus spending.

What he's saying: "Pelosi and Schumer only interested in Bailout Money for poorly run Democrat cities and states. Nothing to do with China Virus! Want one trillion dollars. No interest. We are going a different way!" Trump tweeted.

House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer argued Friday that July's jobs report showcased the urgent need for Congress to pass another coronavirus stimulus.

The state of play: Congressional Democrats and Republicans remain miles apart on stimulus talks as the August recess looms. Schumer and Pelosi have argued for another massive package while Republicans eye a more pared-back solution — and President Trump has threatened executive action amid the logjam.

TikTok has become a Rorschach test for how U.S. politicians view China, with little consensus on the specifics of its threat to homeland security.

The big picture: Much of what D.C. fears about TikTok is fear itself, and that's reflected in President Trump's executive order to ban the app by Sept. 20 if it's not sold by parent company ByteDance — alongside another focused on Chinese messaging app WeChat and its parent company Tencent.

The Justice Department announced Thursday that it will send federal law enforcement agents to St. Louis, Mo., and Memphis, Tenn., to help stem violent crime.

Why it matters: The Trump administration's deployment expands its "Operation Legend" program as President Trump has blamed spikes of violence across the U.S. on activists' efforts to "dismantle and dissolve" local law enforcement. Democrats have accused Trump of targeting Democratic-run cities as part of his "law and order" messaging strategy following the police killing of George Floyd.

House Speaker Nancy Pelosi tore into her Republican colleagues on Thursday for their approach to negotiating the next coronavirus stimulus package, telling CNBC's Jim Cramer: "Perhaps you mistook them for somebody who gives a damn."

Why it matters: Democrats and the Trump administration have not agreed to any "top-line numbers" and remain "trillions of dollars apart," White House chief of staff Mark Meadows told reporters on Thursday.
