President Donald Trump has formally told members of Congress that U.S. “military action” against Iran restarted last week, ending what the letter described as a monthslong ceasefire, according to correspondence obtained by CBS News.
CBS News reported on May 10 that it had reviewed the president’s written notification, which stated that military operations had resumed and that lawmakers were being officially informed. The report did not detail the specific nature, location, or scale of the renewed action, but framed the move as a clear break from the previous pause.
The Guardian, in separate coverage on May 10 of a related Supreme Court ruling involving Trump-era actions, also referenced the president and the renewed focus on his conduct in office, reinforcing that the notification to Congress is part of a broader moment of scrutiny around presidential power. However, The Guardian’s reporting did not provide additional operational details about the Iran action itself.
What the notification said and how it reached Congress
According to CBS News, the president’s letter explicitly informed lawmakers that military action against Iran had “formally restarted” the previous week. The outlet described the correspondence as an official notification to Congress, but did not publish the full text or specify which members or committees first received it.
CBS News reported that the letter marked the end of a ceasefire that had been in place for several months. The report did not identify the original start date of that ceasefire, the terms under which it had been observed, or whether it had been publicly announced at the time it began.
The CBS account did not indicate whether the notification was framed under the War Powers Resolution, the 1973 law that requires presidents to inform Congress when U.S. forces are introduced into hostilities. The report instead summarized the letter’s central point: that military action had resumed and Congress was being told after the fact that this restart had occurred the prior week.
Why the restart matters for Congress and oversight
The fact that the president formally notified Congress, as reported by CBS News, places the development squarely within the ongoing debate over the legislature’s role in authorizing and overseeing the use of force abroad. While CBS did not quote lawmakers reacting to the letter, the very act of written notification signals that the administration considered the renewed action significant enough to record in official communications with Capitol Hill.
The Guardian’s separate reporting on May 10, focused on a Supreme Court ruling involving victims of what it described as a “Trump purge” in the civil service, underscored how Trump-era decisions are being tested in the courts. In that story, critics called the ruling a “dagger in [the] heart” of civil servants. Though that article did not center on Iran, it highlighted the Supreme Court’s role in defining the limits of presidential authority, a backdrop that is relevant as Congress receives notice of renewed military operations.
Together, the CBS and Guardian reports show Congress, the president, and the Supreme Court intersecting around questions of executive power. In this case, the Iran notification adds a foreign military dimension to a domestic legal and institutional debate.
What is known — and not yet known — about the Iran action
CBS News’ May 10 report is the primary public account describing the restart of military action against Iran. It states that operations resumed last week and that a ceasefire lasting several months has ended. Beyond that, key operational details remain undisclosed in the reporting.
The CBS account does not specify:
- What kind of military action has resumed (for example, airstrikes, naval operations, cyber operations, or other activities)
- Where any such actions took place
- Whether U.S. forces suffered casualties or inflicted casualties
- Whether the operations were unilateral or involved partners
The Guardian’s coverage, while reinforcing that Trump and his exercise of presidential power are under intense public and legal scrutiny, does not add factual detail about the Iran operations themselves. As a result, the current public picture of the restarted action is limited to the fact of its resumption, the existence of a prior ceasefire, and the president’s formal notice to Congress.
How the Supreme Court fits into the moment
On the same day CBS News reported on Trump’s notification to Congress about Iran, The Guardian covered a Supreme Court decision involving civil servants who said they were targeted in what the outlet called a “Trump purge.” Victims quoted in that article described the ruling as a “dagger in [the] heart” to the civil service.
That Supreme Court case, as reported by The Guardian, is separate from the Iran developments. However, it highlights that Trump-era actions are being reviewed and, in some cases, upheld or constrained by the Court. In parallel, Congress is now on record as having been told that military action against Iran has resumed, placing another Trump decision within the formal checks-and-balances framework.
While neither CBS nor The Guardian directly link the Supreme Court’s ruling to the Iran notification, both stories involve the same central figure — President Trump — and point to institutions, namely Congress and the Court, that are tasked with responding to or reviewing presidential decisions.
What to watch next
In the coming days and weeks, additional congressional activity is likely to indicate how lawmakers are responding to the president’s notification. Key signs to watch include whether relevant committees schedule briefings, request classified sessions, or seek further written explanations from the administration about the nature and scope of the renewed military action, building on the initial letter described by CBS News.
Public statements from congressional leaders and committee chairs may also clarify whether members believe existing authorizations cover the reported operations, or whether they think new debate is needed. Any move by lawmakers to introduce resolutions, request hearings, or ask for more detailed reporting would signal how seriously they view the restart of hostilities described in the president’s letter.
Finally, court dockets and Supreme Court activity, highlighted by The Guardian’s reporting on the civil service case, could remain an important barometer of how Trump-era decisions are being tested. While no specific legal challenges to the Iran action have been reported in the available coverage, future filings or rulings related to presidential war powers and executive authority would help define the boundaries within which any renewed military operations must operate.
