Donald Trump has delivered a speech at his “Salute to America” event in Washington DC, as the country celebrates Independence Day.
Earlier in the day on Thursday, he pleaded for people to attend his Fourth of July celebration amid fears of a low turnout and concerns that the heavy tanks on display could damage the Lincoln Memorial.
A new Morning Consult poll revealed the president to be losing support in key states he won in 2016, including Michigan, Wisconsin, Iowa, Pennsylvania, Arizona, Ohio and Florida, as his Republican opponent Justin Amash announces his resignation from the GOP in opposition to Mr Trump's "dehumanising rhetoric".
Undeterred, the president has been on angry form on Twitter, hitting out at migrants over reports of squalid conditions in US border detention centres and warning Iran against making threats by issuing one of his own: “They can come back to bite you.”

Crowd size has been a sore point for the president, who has repeatedly claimed that attendance at his inauguration in January 2017 was the highest ever seen in the US capital, despite extensive documentary evidence to the contrary.
The president is set to speak in front of the Lincoln Memorial from 6.30pm EST to a ticket-only crowd of Republican donors, administration and campaign officials, family members and those gathering either to support him or protest his policies. Storms have been forecast for the area on what promises to be a scorching and humid day, meaning Trump's parade could quite literally be rained on.
His "show of a lifetime" promises tanks on display, an Air Force flyover and a massive fireworks display but has been criticised by his opponents as authoritarian and narcissistic and for seeking to turn a non-partisan national holiday into a campaign rally.
There is no such historical marker on Thursday for President Trump, who for the past two years has sought a moment to orchestrate a display of America's military prowess in line with the customary spectacle France likes to lay on to mark Bastille Day.
Trump sounded a defensive note on Wednesday, tweeting that the event's cost "will be very little compared to what it is worth".
"We own the planes, we have the pilots, the airport is right next door, all we need is the fuel," he said, referring to Maryland's Joint Base Andrews, home for some of the planes that are to fly over the Mall on Thursday.
"We own the tanks and all. Fireworks are donated by two of the greats. Nice!"
Trump glossed over the expense of shipping M1 Abrams tanks and other fighting vehicles to Washington by rail from Fort Stewart, Georgia, and guarding them for several days, among other costs.
The US Air Force said it costs $122,311 (£96,500) an hour to fly a B-2 bomber, which is making the round trip from its home at Whiteman Air Force Base in Missouri.
Officials said the flight will be considered a training event, with the cost already budgeted. The per-hour flying cost of the F-22 fighter is $65,128 (£51,360).
"I think the president’s trying to honor himself, and, again, my worry is it ultimately makes us look smaller.
