WASHINGTON -- President Trump said the risk to Americans from coronavirus remains very low, and he put Vice President Mike Pence in charge of federal response efforts as concern about the outbreak grew among lawmakers and as cities nationwide made fresh preparations.

On Capitol Hill, leaders from both parties said they would seek billions of dollars in emergency spending beyond the $2.5 billion plan President Trump has proposed.

"'We're very, very ready for this, for anything, whether it is going to be a breakout of larger proportions or whether or not we're at that very low level," Mr. Trump said at an hourlong White House briefing surrounded by administration health officials and the vice president. "Because of all we've done, the risk to the American people remains very low."

Officials have also discussed having the Food and Drug Administration grant authorization to state and local health labs to design their own coronavirus tests without going through the current regulatory process, a source of frustration for public-health officials, according to people familar with the conversations. The Centers for Disease Control and Prevention has been working to roll its test kits out to other public-health labs, but the process was stalled when some labs got inconclusive results. About 445 people have been tested

The fast-moving developments came a day after a top CDC official, Nancy Messonnier, warned businesses, schools and communities to plan for potential outbreaks. Mr. Trump, who has sought to project confidence that the number of cases in the U.S. will be contained, was angered by the tone of the remarks, according to two people familiar with the discussions.

U.S. stocks fell for the fifth consecutive session Wednesday as investors continued to assess the economic impact of the coronavirus epidemic. Health and Human Services Secretary Alex Azar said the U.S. should expect more coronavirus cases, and Mr. Trump called on schools to prepare "just in case." He said he didn't think it was inevitable that the virus would spread across the U.S.

"This will end," Mr. Trump said.

In the U.S., 15 locally diagnosed cases have been confirmed, including a new one Wednesday in California, with an additional 42 from the outbreak on the Diamond Princess cruise ship in Asia and three among Americans who returned from China aboard U.S.-chartered flights. The new case in California involved an individual who reportedly didn't have a travel history or exposure to another known patient with the illness. If confirmed, it would be the first case of spread in a community without a clear explanation.

More than 2,700 people have died globally as a result of the virus, which is believed to have originated in China and has spread to Iran, Italy, South Korea and other countries.

While the U.S. has imposed travel restrictions on China, Mr. Trump said "it's not the right time" to limit travel to and from other countries with major outbreaks.

U.S. cities have begun preparing for possible outbreaks. In San Francisco, officials are working with hospitals and clinics to identify rooms for isolating coronavirus patients and to screen patients for travel history and symptoms. City officials also told schools to start planning to manage potential closures.

"Although there are still zero confirmed cases in San Francisco residents, the global picture is changing rapidly, and we need to step up preparedness," said Mayor London Breed.

In Texas, Dr. Umair A. Shah, director of Harris County Public Health, said a team of doctors, scientists and outreach personnel have been meeting daily for nearly two months to coordinate readiness in the Houston area.

New York City Mayor Bill de Blasio said there are 1,200 public hospital beds that can be made available to patients who need isolation without affecting current health needs. New York Gov. Andrew Cuomo said he is seeking an emergency appropriation of $40 million for the state's Department of Health to use for equipment and personnel.

"We're preparing, but this situation is not a situation that should cause undue fear among people," Mr. Cuomo said.

The virus's spread is worrying some in the Trump administration, who fear the consequences of a large-scale outbreak in the U.S., both in terms of public health and the president's prospects for re-election if the response falters. Planning for the coronavirus has been hampered by haphazard communications between states and the federal government, according to people familiar with the planning and some Democratic state leaders.

Some state leaders said the lack of a coronavirus czar to head operations had Trump administration agency heads and advisers clashing over who is in charge.

A federal coronavirus task force led by Mr. Azar has been meeting daily. Mr. Pence will take over coordinating within the federal government and with state governments.

Some Republicans, including Sens. Rick Scott of Florida and Mitt Romney of Utah, have joined Democrats in calling for a czar to supervise operations.

Mr. Azar has faced criticism for his handling of the U.S. response to the virus and has butted heads with some administration officials, according to people familiar with the matter. A former drug company executive who has worked on disease outbreaks as an HHS official in the George W. Bush administration, Mr. Azar was doing a "fantastic job," Mr. Trump said.

Mr. Trump, who returned Wednesday morning from a trip to India, has accused Democrats and the media of exaggerating the threat.

Democrats have criticized the president for eliminating a global health position on the National Security Council that Mr. Obama established after the Ebola crisis. The administration's recently released budget request to Congress proposes large cuts to key agencies overseeing the coronavirus response, including a nearly 16% cut to the CDC and 10% at HHS. Mr. Trump said he didn't regret the proposed cuts.

On Capitol Hill, negotiations on funding a response to the disease began, with staff from both chambers and parties meeting Wednesday. The Trump administration's proposal to spend at least $2.5 billion on combating coronavirus -- with $1.25 billion in new funds and at least $1.25 billion in repurposed funds -- has disappointed members of both parties.

"We will work on it, but it will be higher than what they've got," Senate Appropriations Chairman Richard Shelby (R., Ala.) said, referring to the Trump proposal. "We will make sure that we've got the resources without any doubt."

Senate Minority Leader Chuck Schumer (D., N.Y.) proposed his own $8.5 billion emergency spending package on Wednesday. House Minority Leader Kevin McCarthy (R., Calif.) said he expected the package to come in around $4 billion.

Mr. Trump said he would leave it to Congress to set the amount, and "we'll take it."

Mr. Azar earlier Wednesday stressed the low number of diagnosed cases even though problems with coronavirus tests have delayed further detection of the disease.

Mr. Azar said money from the administration's emergency funding request would be used for a fund at the CDC to reimburse state and local agencies.

Already, the administration has transferred about $140 million from the Department of Health and Human Services toward fighting the virus, including $60 million from the National Institutes of Health and $40 million from a program that helps low-income Americans with energy bills.
