Joe Biden will deliver a speech at 2pm, the White House just announced.

Chances are it will be to announce his executive order on immigration, but his administration did not specify what Biden will talk about.

Joe Biden, of course, has his own problems, and one of them is the large number of migrant arrivals on the southern border that has taken place during his term. There are a number of reasons why this has occurred, but polls have shown that the trend is plainly a concern for voters, and Republicans have seized on it to argue Biden is unfit for office.

Earlier this year, the Senate tried to pass legislation that Biden said would help his government better manage the migration wave, but that was shut down by Republicans acting at the behest of Donald Trump. The Guardian’s Lauren Gambino reports that the president will today unveil a policy that will allow him to temporarily close the southern border to new asylum seekers. Here’s more:

Joe Biden on Tuesday was set to announce an executive order that would reportedly temporarily shut down the US-Mexico border to asylum seekers attempting to cross outside of lawful ports of entry, when a daily threshold of crossings is exceeded.

The move comes amid rising public concern over the number of migrants crossing into the US, with polls showing a majority of Americans dissatisfied with the president’s handling of the border. The White House has been under immense pressure from Republicans and some Democrats to reduce the number of migrants arriving at the southern border.

Many progressive and Hispanic lawmakers expressed alarm at the sweep of the order, the most aggressive border move taken by the administration so far.

Speaking to donors in White Plains, New York, Joe Biden yesterday said this year’s presidential campaign would be like no other, thanks to Donald Trump’s felony conviction.

“Folks – the campaign entered uncharted territory last week. For the first time in American history, a former president that is a convicted felon is now seeking the office of the presidency,” Biden said.

Not since 1892 has an incumbent president faced a challenge to a second term from a former president. However, until Trump, no American president, current or former, has ever been convicted of a crime.

Speaking to donors at the event hosted by HBO chief executive Richard Plepler, Biden reiterated his argument that Trump would harm America’s democracy, if re-elected.

“The threat Trump poses would be greater in a second term,” Biden said, describing his predecessor as “unhinged”.

“Just listen to his rantings. He wants to, in his words, be a dictator in one day,” the president added.

Good morning, US politics blog readers. Joe Biden went on the attack against Donald Trump last night, with a new and potentially potent weapon: his conviction on business fraud charges. At a campaign event in New York, the president described Trump as a “convicted felon”, and said, “This guy does not deserve to be president whether or not I’m running.” The remarks comes after months of polling that showed the president trailing his predecessor in surveys of the swing states that will determine the election. But all of those were conducted before a jury found Trump guilty of falsifying business records to conceal hush-money payments ahead of the 2016 election, a historic conviction that Biden’s campaign is clearly hoping will make voters turn their backs on the ex-president.

Only a few polls have been released since the Thursday’s verdict, but they contain signs that Trump’s conviction has dented his support with independents, and the so-called “double haters” – people who like neither candidate. Both groups are seen as pivotal to determining the election, and we’ll see if the trend persists in the months of campaigning to come.

Here’s what else is happening today:

• Biden is expected to today sign an executive order allowing the government to turn away asylum seekers from the border, if crossings reach a certain average level. The measure represents an unprecedented crackdown by a Democratic president, and comes as he tried to blunt Republican attacks on his immigration record.

• House Republicans have summoned attorney general Merrick Garland for a hearing aimed at holding him in contempt for not turning over recordings of Biden’s interview with a special counsel. The White House last month asserted executive privilege over the audio.

• Senate Democrats will hold a hearing exploring how the health outcomes of women nationwide have changed in the two years since the supreme court’s conservatives overturned Roe v Wade.
