Feb 4: Americans on Monday kicked off the first vote of the 2020 presidential race as the midwestern state of Iowa began its caucuses, the closely-watched first step in deciding which Democrat will face incumbent Donald Trump in November's election.

The two frontrunners, left-wing Senator Bernie Sanders and former Vice President Joe Biden face a key test in the sparsely populated state, with a handful of others looking to make their mark to give their campaigns momentum.

The Iowa vote is a critical early look at the viability of the 11 Democratic candidates still in the race - even though just 41 Iowa delegates are up for grabs, a fraction of the 1,991 needed to secure the party nomination in July.

Iowa Democrats filed into nearly 1,700 caucus sites - schools, libraries, churches, mosques and meeting halls with Sanders and Biden in the lead in the state, followed by former South Bend, Indiana mayor Pete Buttigieg and Senator Elizabeth Warren, who is also on the left of the party.

But polling has fluctuated and Iowa's quirky caucus system - where voting is not by secret ballot but by public declaration for a candidate - makes the night hard to predict.

Luke Elzinga, a volunteer for Sanders, appeared early at Lincoln High School in Des Moines which was converted into a caucus location.

"I think he really inspires a lot of young people, a lot of disaffected voters who might not otherwise turn out," Elzinga, 28, told AFP news agency shortly before the caucusing began.

"And so I think he's the best candidate to beat Trump."

Three candidates - Sanders, Warren and Amy Klobuchar - have faced the unprecedented scenario of spending much of the past two weeks tethered to Washington for the impeachment trial of Trump instead of on the campaign trail in Iowa.

Even as candidates sought to make 11th-hour impressions on undecided voters, the senators were obligated to return to Washington for the trial's closing arguments on Monday.

Defeating Trump

In a vote scheduled for Wednesday, Trump is almost certain to be acquitted by the Republican-led upper house on charges of abuse of power and obstruction of Congress.

For Democrats, second-tier hopefuls Klobuchar and tech entrepreneur Andrew Yang look to outpace expectations and seize momentum heading into the next contest in New Hampshire on February 11.

Earlier on Monday Biden - who still holds the lead in national polls - brought pizza to a field office in a strip mall near Des Moines to thank volunteers.

"I'm feeling good about today," he said.

Like many candidates, Biden spent the weekend crisscrossing Iowa in a final push to convince undecided voters he is best placed to accomplish Democrats' number one goal: defeating Trump.

The president has not stood idly by. On Sunday he branded Biden "Sleepy Joe" and described Sanders as "a communist," previewing a likely line of attack were Sanders to win the nomination.

Unlike secret ballot voting, caucus-goers publicly declare their presidential choice by standing together with other supporters of a candidate.

Candidates who reach 15 percent support earn delegates for the nomination race while supporters of candidates who fall short can shift their allegiance to others.

Turnout is critical, and candidates and their representatives will seek to persuade voters on issues including healthcare, taxes and ending Washington corruption.

One key candidate who has opted not to contest in Iowa is billionaire businessman Michael Bloomberg, who entered the race in November but has surged into fourth place in RealClearPolitics' national polling average.

The former New York mayor, who has spent more than $300m on advertising, according to Advertising Analytics, is focused on running a national campaign with particular emphasis on states that vote on "Super Tuesday," on March 3.

Washington, Apr 18: The United States on Friday passed 700,000 confirmed coronavirus cases, according to a tally maintained by Johns Hopkins University.

With the highest number of cases and deaths of any country in the world, the US had recorded 700,282 cases of COVID-19 and 36,773 deaths as of 8:30 pm (0030 GMT Friday), according to the Baltimore-based university.

That marked an increase of 3,856 deaths in the past 24 hours, but that figure likely includes "probable" virus-linked deaths, which had not previously been counted.

This week, New York City said it would add 3,778 "probable" virus deaths to its official count.

The US Centers for Disease Control and Prevention gave a toll Friday night of 33,049 dead, including 4,226 probable virus-linked deaths.

The United States has seen the highest death toll in the world in the coronavirus pandemic, ahead of Italy (22,745 deaths) although its population is just a fifth of that of the US.

Spain has recorded 19,478 deaths, followed by France with 18,681.

Trump announces $19 billion relief for farmers amid COVID-19 epidemic

President Donald Trump on Friday announced a $19 billion financial rescue package to help the agriculture industry weather the staggering economic downturn sparked by measures to defeat the coronavirus.

Trump told a press conference the government "will be implementing a $19 billion relief program for our great farmers and ranchers as they cope with the fallout of the global pandemic."

The program will include direct payments to farmers, ranchers and producers who Trump said have experienced "unprecedented losses during this pandemic."

Agriculture Secretary Sonny Perdue said US farmers have been hit hard by a sharp shift in demand, as schools and restaurants close and more Americans eat at home.

That has disrupted the food supply chain, forcing farmers in many places to destroy dairy output and plow under crops that no longer have buyers.

"Having to dump milk and plow under vegetables ready to market is not only financially distressing, but it's heartbreaking as well to those who produce them," Perdue said.

Perdue said some $3 billion of the money would go to buying produce and milk from such farmers, and redistribute it to community food banks.

Millions of Americans have recently turned to food pantries for meals and groceries after losing their jobs.

New Delhi, Mar 4: The Supreme Court on Wednesday revoked the ban of cryptocurrency imposed by the Reserve Bank of India (RBI) in 2018.

Pronouncing the verdict, the three-judge bench of the apex court said the ban was 'disproportionate'.

The bench included Justice Rohinton Fali Nariman, Justice S Ravindra Bhat and Justice V Ramasubramanian.

The Internet and Mobile Association of India (IAMAI), whose members include cryptocurrency exchanges, and others had approached the top court objecting to a 2018 RBI circular directing regulated entities to not deal with cryptocurrencies.

Advocate Ashim Sood, appearing for IAMI, submitted that Reserve Bank of India lacked jurisdiction to forbid dealings in cryptocurrencies. The blanket ban was based on an erroneous understanding that it was impossible to regulate cryptocurrencies, Sood submitted.

The petitioners had argued that the RBI's circular taking cryptocurrencies out of the banking channels would deplete the ability of law enforcement agencies to regulate illegal activities in the industry.

IAMAI had claimed the move of RBI had effectively banned legitimate business activity via the virtual currencies (VCs).

The RBI on April 6, 2018, had issued the circular that barred RBI-regulated entities from "providing any service in relation to virtual currencies, including those of transfer or receipt of money in accounts relating to the purchase or sale of virtual currencies".
