The big news last week was the US passing its $61bn (£48.1bn) aid package for Ukraine after months of delay.
The House of Representatives - which had been blocking the military aid - approved the package the weekend before, but it was officially signed into law on Wednesday.
Joe Biden said it had been a "difficult path" but America eventually "rose to the moment" as it was signed into law.
Long-range missiles from US already in use in Ukraine
The initial package of aid will include long-range missiles, the US confirmed - but then it emerged that such missiles had already been provided in "secret".
Kyiv has used long-range ballistic missiles from the US against Russia twice this month, according to NBC News.
Three US officials told Sky News's partner network on Wednesday that Ukraine first used the Army Tactical Missile System - dubbed ATACMS - on 17 April.
It has a range of about 187 miles.
Long-range weaponry has previously been held back for fear it would be used in attacks inside Russia - and concerns over the potential for NATO missiles landing there to provoke a wider escalation.
Why was the bill finally approved?
The change of heart from House Republicans came after a meeting between the Republican speaker of the House, Mike Johnson, and Donald Trump, whose supporters have been vocal in their opposition to aid for Ukraine.

'Urgently' needed Patriot missiles
A second military aid package worth $6bn (£4.8bn) - which includes Patriot missiles - was also approved by the US.
It includes more munitions for the National Advanced Surface-to-Air Missile Systems and gear to integrate Western air defence launchers, missiles and radars into Ukraine's existing weaponry, much of which dates back to Soviet times.
Spain will also reportedly send Patriot missiles as a way to "step up" its "commitment to Ukraine," according to a Spanish diplomatic source.
Volodymyr Zelenskyy had previously asked for at least seven Patriot systems to protect Ukrainian cities, saying they were needed "urgently".
Fighting intensifies in eastern Ukraine
And this is why Ukraine says it desperately needs more military aid...
On Sunday, Ukraine's top general said fighting had intensified in the east of the country, with troops falling back in three areas.
Oleksandr Syrskyi said Russian troops achieved "certain tactical successes" in the villages of Berdychi, Semenivka and Novomykhailivka, all of which are in the eastern Donetsk region.
Russia has been pushing forward in Donetsk, particularly in the area of Avdiivka.
Ukraine says it is outgunned and outmanned, and as a result is slowly losing ground.
Reports also suggest Russia has set its sights on the strategic town of Chasiv Yar which, if captured, would make it easier for Moscow to advance further in the east.
Potential Russian summer offensive
Elsewhere, a commander from Ukraine's National Guard has said Russia is planning "unpleasant surprises" in a potential summer offensive.
Oleksandr Pivnenko told news outlet Liga Net that, as part of this, the National Guard does not rule out Russian attempts to target Kharkiv - the country's second-largest city.
Kharkiv and the surrounding region have been the focus of recent attacks from Moscow, experiencing the most intense strikes.
UK funding
On Tuesday, Rishi Sunak announced a £500m military aid package for Ukraine - the UK's largest military pledge to the country.
In a speech in Warsaw, Poland, Mr Sunak said: "An investment in Ukraine is an investment in our security."
The prime minister also said he would put the UK's own defence industry "on a war footing" as he confirmed an increase in defence spending to 2.5% of national income by 2030.
Russia-Finland tensions
Russia hit out at NATO exercises near its border with Finland, warning they raised the risk of "possible military incidents".
Russian foreign ministry spokeswoman, Maria Zakharova, told the RIA state news agency the drills are "provocative".
Commenting on Friday's drills, Ms Zakharova said: "NATO military exercises near the Russian borders are provocative in nature.
"Their task is to exert military pressure on the Russian Federation through a demonstration of force."
She added: "The drills... increase the risks of possible military incidents."
